This how-to tutorial shows you how to tweak the Windows 10 Registry file to force the deletion of pagefile.sys every time you shut down your computer, thereby removing any potential security vulnerabilities. With this method, the next time you start your Windows 10 computer, the paging file will be recreated with new data.
Disclaimer: Editing the Windows Registry file is a serious undertaking. A corrupted Windows Registry file could render your computer inoperable, requiring a reinstallation of the Windows 10 operating system and potential loss of data. Back up the Windows 10 Registry file and create a valid restore point before you proceed.
How to delete the pagefile.sys file in Windows 10
To see what your current paging file settings are, follow these steps:
1. Open File Explorer and right-click Computer.
2. Select Properties.
3. Click on Advanced system settings (Figure A).
4. Click the Settings button under the Performance section and then click the Advanced tab. You should see a screen similar to Figure B. Your current settings for the Windows 10 paging file will be displayed under the Virtual Memory section. In the example, the paging file is currently set to be about 16 GB.
5. Click OK a couple of times to close those screens.
6. Start the Registry file tweaking process by typing “regedit” into the Cortana search box on the Windows 10 desktop.
7. Click the entry in the search results that refer to the Registry Editor program (regedit.exe).
8. With the app open, navigate to this specific key (Figure C):
Bots—software applications that run scripts over the internet—make up more than half of all internet traffic. This creates a major blind spot for IT security teams, as 79% of CISOs and other security leaders said they can’t tell for certain if web traffic comes from humans or bots, according to a recent Radware report.
It’s key to understand that there are good bots and bad bots, said Reid Tatoris, vice president of product outreach and marketing at Distil Networks. “‘Good bots enable search engines to index web content, price comparison services to save consumers money, and market researchers to gauge sentiment on social media, for example,” Tatoris said. These also include chatbots, and search engine and social media bots.
Meanwhile, “‘bad bots are used to conduct a variety of harmful activities, such as denial-of-service attacks, competitive data mining, online fraud, account hijacking, data theft, stealing of intellectual property, unauthorized vulnerability scans, spam, and digital ad fraud,” Tatoris said. These include impersonators, scrapers, hackers, and spambots.
Bad bots are used by many different groups, ranging from organized crime to state actors pushing a political agenda to people trying to make money. But there are ways to tell if your website has been visited by a bot and keep it safe.
Here are five ways to spot a bot.
1. Monitor login attempts
One of the most profitable uses of bots for an attacker is via credential stuffing, the mass-scale automated testing of username and password combinations across multiple websites, according to Patrick Sullivan, Akamai director of security technology and strategy. When successful matches are discovered, attackers use these logins to take over the account for fraud or to resell the confirmed credentials.
One simple step to detect bots is to monitor macro-level success and failure rates of login attempts, Sullivan said. “Regardless of how advanced the bots are and how difficult they are to identify, credential stuffing generates high levels of failed logins,” he added. “Even if fraudsters are careful enough not to trigger account lockouts, they will generate failed logins, which are early warning signs of bot activity.”
2. Check your server logs
One of the first steps to identifying a bot is to check your server logs, said Andrew Swindlehurst, systems admin at PPC Protect Limited. “Every computer that connects to your website will leave a trace on your server,” Swindlehurst said. “With logs of every user that has connected to your website, you can then begin to analyse the users for any suspicious bots.”
Most bots will visit the same website regularly, even several times a day, he said. “If you keep seeing the same IP address pop up on your logs, then the chances are they could be a bot,” he added. You can check the IP addresses, location, and hostname manually, using a website like IPAvoid. If the IP is included on a blacklist or is not a residential address, there’s a strong chance that it’s a bot.
3. Check your email outbox
If your Sent messages folder contains messages that have been drafted, sent, or returned to you that you did not write, this is a tell-tale sign that you may have been visited by a bot, said Steve Pritchard, search content manager at giffgaff. “The bot is then intending to infiltrate the computers of your email contacts by sending them emails riddled with malware,” Pritchard said.
4. Watch if your website slows down or crashes
“Bots move fast across websites and do so in hoards, so you get a lot of server requests per second, which can overload the system and cause a major slowdown in loading times,” said Tatoris. “The result is that you end up spending more money on server costs for traffic that doesn’t translate into any benefit for your business. In addition, any humans who try to visit your site or make a purchase at a time when the site slows down will typically leave and take their business somewhere else.”
5. Check if your site content shows up elsewhere on the internet
Bots can sometimes copy website content and post it elsewhere without permission, Tatoris said. “The site Copyscape can help you to determine whether or not any of your site information has been posted elsewhere on the internet,” he added. “If you enter in the URL of a page from your website into their search field, they will return any pages that have high percentage matches to the content on the referenced page. While this isn’t a sure fire way of telling whether your content has been copied, it can potentially give you some idea.”

Nothing is more frustrating than trying to help someone solve a problem from a distance, especially when the person suffering through the problem is technically unsophisticated. Remote assistance software is an excellent tool, but it’s not always practical for solving intermittent issues.
Instead of listening to vague descriptions of error messages and buttons, introduce your remote contact to the Problem Steps Recorder. To start the program, type PSR in the search box (Windows 10) or in the Run box (Windows 7) and press Enter.
The Steps Recorder has just three buttons: Start Record, Stop Record, and Add Comment. Clicking Start Record captures the exact contents of the screen and adds an annotation each time your remote contact performs an action like clicking a mouse button. Teach them to use the Add Comment button if they want to explain what’s happening in their own words.
Armed with that detailed report, you’re likely to have a much more productive support session next time.
What I did was uninstall updates KB3035583, KB2990214, and KB2952664. The first two were mentioned by other users as connected with the Windows 10 upgrade. The third was installed on my computer on 7/31/2015 which is the day the upgrade takeover of my computer began.
THE IMPORTANT THING IS TO ENSURE THAT THESE UPDATES ARE NEVER INSTALLED AGAIN!
Turn off automatic updates. The first and third update are listed as “Important” updates, yet are NOT automatically selected. There is an “Optional” update ‘Upgrade to Windows 10 Pro’ (no KB number) which IS automatically selected—this may be the middle update listed above.
I still find TrustedInstaller.exe running on my computer when I power up, yet it disappears after a while. This process can NOT be ended via Windows Task Manager. There are also files installed on my computer that cannot be deleted without permission from TrustedInstaller which is above any Administrator and System privileges. These files are in the hidden C:\$Windows.~BT folder.
I hope this info is helpful to you.
Another user states:
I had the exact same issue as all of you. Once the Windows 10 install files were downloaded, there was no way to change your mind, you’re in the clutches of Windows Update! Completely ridiculous if you ask me!
Luckily I came up with a solution that worked perfectly for me. I performed a system restore to the first available date prior to July 29th. Once my system was restored, I searched for the above installed updates (KB3035583, KB2990214, and KB2952664) and uninstalled them. After uninstalling, I went back in and “hid” those updates so that they wouldn’t show up when Windows Update would run.
I did all this 2 days ago and my PC is running like a champ as nothing had ever happened!
Hope this helps.
Select the KB3035583 update with a click or a tap and then press the Uninstall button found at the top of the updates list. Confirm that you want to uninstall this update and wait for the process to finish. Then, reboot your device. Now, the “Get Windows 10” app is completely removed from your system.
This utility, which has the most comprehensive knowledge of auto-starting locations of any startup monitor, shows you what programs are configured to run during system bootup or login, and when you start various built-in Windows applications like Internet Explorer, Explorer and media players. These programs and drivers include ones in your startup folder, Run, RunOnce, and other Registry keys. Autoruns reports Explorer shell extensions, toolbars, browser helper objects, Winlogon notifications, auto-start services, and much more. Autoruns goes way beyond other autostart utilities.
Autoruns‘ Hide Signed Microsoft Entries option helps you to zoom in on third-party auto-starting images that have been added to your system and it has support for looking at the auto-starting images configured for other accounts configured on a system. Also included in the download package is a command-line equivalent that can output in CSV format, Autorunsc.
You’ll probably be surprised at how many executables are launched automatically!
Simply run Autoruns and it shows you the currently configured auto-start applications as well as the full list of Registry and file system locations available for auto-start configuration. Autostart locations displayed by Autoruns include logon entries, Explorer add-ons, Internet Explorer add-ons including Browser Helper Objects (BHOs), Appinit DLLs, image hijacks, boot execute images, Winlogon notification DLLs, Windows Services and Winsock Layered Service Providers, media codecs, and more. Switch tabs to view autostarts from different categories.
To view the properties of an executable configured to run automatically, select it and use the Properties menu item or toolbar button. If Process Explorer is running and there is an active process executing the selected executable then the Process Explorer menu item in the Entry menu will open the process properties dialog box for the process executing the selected image.
Navigate to the Registry or file system location displayed or the configuration of an auto-start item by selecting the item and using the Jumpto Entry menu item or toolbar button, and navigate to the location of an autostart image.
To disable an auto-start entry uncheck its check box. To delete an auto-start configuration entry use the Delete menu item or toolbar button.
The Options menu includes several display filtering options, such as only showing non-Windows entries, as well as access to a scan options dialog from where you can enable signature verification and Virus Total hash and file submission.
Select entries in the User menu to view auto-starting images for different user accounts.
More information on display options and additional information is available in the on-line help.
Autorunsc is the command-line version of Autoruns. Its usage syntax is:
Hide Microsoft entries (signed entries if used with -v).
Verify digital signatures.
Show timestamps in normalized UTC (YYYYMMDD-hhmmss).
If VirusTotal check is enabled, show files that are unknown by VirusTotal or have non-zero detection, otherwise show only unsigned files.
Print output as XML.
Query VirusTotal (www.virustotal.com) for malware based on file hash. Add ‘r’ to open reports for files with non-zero detection. Files reported as not previously scanned will be uploaded to VirusTotal if the ‘s’ option is specified. Note scan results may not be available for five or more minutes.
Before using VirusTotal features, you must accept VirusTotal terms of service. See: https://www.virustotal.com/en/about/terms-of-service/ If you haven’t accepted the terms and you omit this option, you will be interactively prompted.
Specifies the offline Windows system to scan.
Specifies the name of the user account for which autorun items will be shown. Specify ‘*’ to scan all user profiles.

On the popular Discovery Channel program “Mythbusters,” hosts Adam Savage and Jamie Hyneman take a legend and deconstruct it to see whether its long-held beliefs are legitimate. They’ve busted all kinds of myths, from Jimmy Hoffa being buried under Giants Stadium (not true) to the ability to kill someone without a trace using an ice bullet (the bullet vaporizes as soon as the trigger’s pulled).
One tall tale they haven’t tackled is that Macs are impervious to malware, so you needn’t worry about cybersecurity solutions. Antivirus and anti-malware protection is for the PCs.
We’re here to bust that myth.
Out the gate we can tell you that it’s true, Macs don’t have the same problem with malware as PCs do. One of the main reasons: sheer numbers. Cybercriminals look at the market and see that the vast majority of folks are on PCs, so they concentrate their efforts on creating malware that will result in the largest return on investment.
But the tide is turning. Macs are now responsible for 7.5 percent of global personal computer sales. In the U.S., Apple is one of the top three PC vendors, just behind HP and Dell. And as creative departments grow in corporate environments (from design and content to programming and testing), more and more businesses are adding larger numbers of Macs to their environments.
The popularity of Macs leads to more cybercriminals wanting to write malicious code for OS X. Although still much lower than PCs, the number of threats targeting Apple operating systems has grown steadily, with a spike in Mac infections observed over the last 18 months. A recent study by Bit9 + Carbon Black found that the number of Mac OS X malware samples detected in 2015 was five times greater than in the previous five years combined.
Forms of malware on Macs
Apple security is fairly tight—OS X has a basic built-in anti-malware feature, and if the machine detects a malicious program, it gets added to the signature database. From that point on, that piece of malware can’t be opened on any Mac, unless the user has explicitly disabled security updates. But clearly some malware is getting through. Which forms?
The worst offender is adware. “There are many different adware programs infecting the Mac right now, and they’re in a constant state of flux,” says Thomas Reed, Director of Mac Offerings at Malwarebytes. “Adware-riddled installers are everywhere, and it’s becoming harder and harder to tell where a safe place is to download software.”
Other forms of malware have given Apple the slip, including Potentially Unwanted Programs (PUPs), Info stealers, Trojans, and even ransomware (KeRanger). While these forms of malware are less prevalent, they can still be quite dangerous. KeRanger was downloaded by around 6,500 people within the 12-hour period that it was available. Some of those users had their data completely destroyed.
How are they getting through?
The main way that adware and malware is getting through on Macs these days is through codesigned apps, using a certificate obtained from Apple. The certificate is either stolen or bought and simply treated as disposable, since it costs only $99. Apple can revoke these certificates if they see them being abused, and they do so quickly when they find a new signed malware. However, Apple doesn’t take a particularly hard stand against most adware, which can persist for a long time with the same certificate.
In addition, video and audio streaming sites and piracy sites often dole out adware. Software download sites distribute installers containing adware that has been added without the permission of the developers. Worse, even some developers’ own sites are guilty of bundling adware. For example, the popular Filezilla FTP client installs adware even when downloaded directly from the official site, and the free version of Avast had (and may still have) an ad-injecting feature in its browser extension.
What happens to your Mac after an infection?
Adware is a serious hassle. Injected ads are intrusive and can contain offensive content. They can also slow down your computer’s performance and result in browser destabilization. Malicious ads can even direct you to tech support scams where you can be scammed out of your money or into installing other harmful software.
But that’s not all, Bob! What else have you won? Info stealers can, obviously, steal your info. And in the case of ransomware, data can be totally destroyed with no shot of getting it back.
Myth: Macs are impervious to malware.
Fact: Macs, while less vulnerable than PCs, are assailable. Their security can be penetrated, especially by cybercriminals looking to deliver adware.
So do you really need a security solution for your Mac? “Although the primary threat right now is adware, it’s still a problem of epidemic proportions,” says Reed. “Even knowledgeable Mac users have been known to fall victim to some kind of adware, so it’s no longer true that you can avoid threats by simply being careful what you download.”
With increases in Mac popularity making OS X more appealing for crooks, plus the already considerable onslaught of adware, it makes sense to install an anti-malware program for your Mac. It should catch what OS X misses and restore your Mac’s performance to the high caliber you expect.
Now what other myths can we bust? Can tooth fillings really receive radio waves?
Gigabit Wi-Fi, 802.11ac, is officially here, but what does that really mean? Here’s my list of the five things you need to know before you invest in this new wireless technology.
1) 802.11ac is not going to give you a Gigabit of throughput
True, 802.11ac access points working with 802.11ac devices will give you faster data transmission feeds than 802.11n. The Wi-Fi Alliance claims that Wi-Fi Certified 802.11ac can deliver data rates up to more than double those of a typical 802.11n network. Practically speaking the Alliance claims that “this means a network can support simultaneously streaming multiple HD-quality videos to multiple devices.”
Fair enough, but in practice you’re not likely to see an 802.11ac reach its theoretical maximum of 1.3 Gigabit per second (Gbps). That’s because the conditions you need to reach that speed requires a laboratory not your office.
To reach the highest speeds you need three data-streams, each of which can run up to 433 Megabits per second (Mbps). A typical 802.11ac access point can support up to eight data streams. Client devices must only support one.
For example, the Samsung Galaxy S4 supports 802.11ac with the Broadcom BCM4335 Wi-Fi chipset. This chipset only supports a single stream so, even in the best of all possible worlds, you’ll only see 433Mbps.
The “unofficial” 802.11ac devices that have been shipping for the last few months, and the first generation of the standard 802.11ac devices aren’t likely to hit these speeds even on a testbed. The fastest speeds here in CNeET/ZDNet land we’ve seen to date came from the NetGear R6300 WiFi Router, which hit a high of 331Mbps.
That’s great, but it’s not gigabit great. It is, however, a lot faster than you’ll see then with any combination of 802.11n gear.
2) Working out the range
802.11ac only supports the 5GHz frequency. The good news about that is that there’s far more room in that frequency spread than there is in the over-used 2.4GHz . The bad news is that a 5GHz signal has less range.
At the same time, 802.11ac has another feature, beam-forming, that gets around the general 5Ghz range problem. For the Wi-Fi access point in your office today, the signal is omni-directional—it forms a communications sphere around the device. With 802.11ac the signal is broadcast directly from the access point (AP) to a specific device and back again.
While no one seems to have published much on what this means, I expect it means that if you’re in an environment with few 802.11ac devices, say eight, you’ll actually see excellent range. But, if you’re in at a convention center with hundreds of 802.11ac devices I suspect you’ll need to be much closer to an AP to get a signal. That said, life is always miserable for Wi-Fi users in hotels and large meetings rooms.
3) Backwards Compatibility
All 802.11ac devices will support older Wi-Fi technologies such as your 802.11n-equipped laptop or even your old 802.11g network bridge. 802.11ac can’t do magic though. For example, if you buy an 802.11ac AP you’ll still be limited to your older devices’ maximum speeds.
Soon, there will be a lot of new gear that supports 802.11ac as clients. If you buy an 802.11ac AP now you’re really buying for future use. It’s not going to do you much good today.
As always you should remember that any network is only as fast as its slowest link. For instance, if you’re buying 802.11ac to improve your Netflix viewing experience and your Internet connect is 10Mbps, it won’t do you a darn bit of good. 802.11n, or even 802.11g, is all you’ll need.
4) AP Channel Conflict Ahoy
Anyone who does any Wi-Fi network management knows that the 2.4GHz range is as crowded as a Best Buy store on Black Friday morning. In theory, you can use up to 14 channels. In practice, to avoid interference, you can only use three or four channels. If you have conflicting channels, you’ll see your network performance go down the toilet. The advantage of 802.11a and 802.11n’s 5Ghz range is that was so much room that you didn’t need to worry about interference. Get worried again.
One of the big ways that 802.11ac gains its speed is by using 80MHz wide channels. In 802.11ac wave two devices–the next generation of 802.11ac, which will start showing up in 2014–the channels will take up 160MHz of frequency. What that means exactly depends on your country, since there are a wide variety of rules on how the 5GHz range can be used. But, in the United States that means 802.11ac will have at most five available channel selections. When 802.11ac second-wave appears it will go down to one or two.
In other words, network administrators should start working out now where they’ll be placing 802.11ac APs, because once more you’ll need to be wary of fouling up performance because of AP interference. And, let’s not talk about that business on the floor below you that’s always munging up your network.
5) 802.11ac requires additional infrastructure
I know, you thought 802.11ac would let you get rid of some of your Gigabit wiring. Nope. Not going to happen. First, as I already explained you’re not really going to get Gigabit speeds out of 802.11ac.
Second, and what many people don’t know, is that second-wave 802.11ac APs will require two, not one, Gigabit Ethernet ports. That just doubled your need for switch ports and cable runs. Oh boy!
Sure, you can get by with one port for now, but remember you’re not really going to have that many 802.11ac clients in 2013. Next year is when they’ll start showing up in large numbers and that’s when the second wave 802.11ac APs will be appearing.
What all this means is that Gigabit Wi-Fi isn’t really here. Faster Wi-Fi is but it’s not really going to take off until 2014 and when it does come deploying it is going to be expensive. I foresee all of us using 802.11n Wi-Fi for years still to come. 802.11ac is not going to roll out quickly.
Ever since Microsoft announced that the upcoming update to Windows 8 will be called as Windows 8.1 and will be available for free to all Windows 8 users, many users who aren’t closely following Microsoft, seem to have confused Windows 8.1 as a service pack.
For those who’re under the impression that Windows 8.1 update is a service pack, a service pack mainly contains previously released updates and fixes, but doesn’t include new features. So, Windows 8 isn’t a service pack as includes new features.
As some of you may know, when Windows Vista was released back in 2007, it didn’t do well in the market and two years later, Microsoft released a polished version of Vista and named it as Windows 7, which went on to become the highest selling operating system in the history. The only major difference (leaving aside features) between Windows 7 and Windows 8.1 is that Windows 7 wasn’t a free update to Vista users and Windows 8.1 is absolutely free to all Windows 8 users.
As the “.1” in the Windows 8.1 name suggests, Windows 8.1 is based on Windows 8. Windows 8.1 update adds hundreds of new features and functionalities to Windows 8 without removing existing features, and is completely free to all Windows 8 users.
Windows 8.1 update is largely based on the feedbacks that Microsoft received by millions of Windows 8 users over the last year. According to Microsoft, this update will encourage XP, Vista, and Windows 7 users to upgrade to the newest version of Windows.
One can say that Windows 8.1 is what Windows 8 should have been, or we can also say that “.1” completes Windows 8!
Windows 8.1 adds the missing Start button to easily switch to the Start screen, an option to boot directly to desktop by skipping Start screen, settings to customize the Start screen, option to automatically set desktop background as Start screen, an easier way to shutdown and restart PC, and hundreds of other features.
Go through the below chart to know some of the key features present in Windows 8.1 that aren’t part of Windows 8:
Microsoft hasn’t exactly been endearing themselves to tech geeks everywhere lately, with all the privacy concerns and other issues. And now they are automatically downloading all of Windows 10 to your Windows 7 or 8 PC, whether you asked for it or not.
To be clear, they aren’t automatically installing Windows 10, but they are downloading the entire installer, which is at least 3 GB, which takes up a lot of drive space, and also wastes your network bandwidth. For people who don’t have unlimited bandwidth, this can seriously cost you a lot of money.
According to a statement provided to The Register by Microsoft, their explanation is that they think this is a better experience:
“For those who have chosen to receive automatic updates through Windows Update, we help customers prepare their devices for Windows 10 by downloading the files necessary for future installation. This results in a better upgrade experience and ensures the customer’s device has the latest software.”
So this only affects people who have automatic updates enabled, but that’s almost everybody since automatic updates are on by default and are rather important for security reasons — the flood of critical security patches in the last year has shown that it’s probably a good idea to leave automatic updates enabled.
But downloading an entire operating system “just in case” you might want to upgrade to it instead of simply waiting for people to decide to opt in — that isn’t the type of behavior that we want.
Make Windows 10 Stop Downloading the Easy Way
If you want a really simple and easy way to get rid of the “Get Windows 10” icon and stop your PC from downloading Windows 10, you can download a little piece of freeware called GWX Control Panel from a developer that isn’t happy with this nonsense either.
Download it, run it, and then click the “Disable Get Windows 10 App (permanently remove icon)” button. And then click the “Disable Operating System Upgrades in Windows Update” button too for good measure.
You’ll have to reboot, but at the end, the icon will be gone and your computer shouldn’t get the upgrade. And luckily you can click those buttons again to put things back the way they were.
How to Block Windows 10 from Downloading (Hopefully)
Unfortunately, there’s no magic button to click to stop Windows 10 from downloading. In fact, you’re going to have to install a special patch from Microsoft to keep them from making you download something else. And that’s if you believe Microsoft’s support documentation, which says that you can block the Windows 10 upgrade this way.
We haven’t been able to absolutely prove that this will stop Windows 10 from downloading because it’s hard to say that this is working just because Microsoft hasn’t forced us to download 3GB of files we didn’t ask for.
This is one of those instances where we normally would avoid writing on the topic, since too much is up in the air and we like to be accurate at all times. So please excuse us if this doesn’t work for you.
You’ll need to install this patch from Microsoft’s website (from what we can tell you’ll need to be on Windows 8.1 and not 8 to install the patch), so pick the version for your OS, install it, and reboot.
You’ll probably have to create the WindowsUpdate key on the left-hand side, which you can do by right-clicking the Windows node. Click on that new key, and then create a new 32-bit DWORD called DisableOSUpgrade on the right-hand side, and give it a value of 1.
If you already have the folder, which is hidden on the root of your system drive, you’re going to want to follow these instructions over on AddictiveTips to remove it. We haven’t verified these instructions, as we already upgraded most of our computers to Windows 10, and we don’t have the folder on any of our test VMs.
