How to Stop Windows 10 Upgrade

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.



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.

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.
