Blocking Windows 10 From PCs

windNOws-10-logoSo there are a lot of ways to block the Windows 10 utility (GWX) from installing through Windows Update. Microsoft is getting more persistent with their update and it’s starting to make a lot of people angry. They want the world on Windows 10 but sometimes you don’t want or can’t upgrade. This is a simple fix to block GWX from installing – even if Microsoft tries to slipstream it into other updates like Internet Explorer (which they’ve recently done).

Open Explorer and go to C:\Windows\System32 and find or create a folder called GWX. Right click on the folder and go to Properties. Click on the Security tab and then click on Advanced to access special permissions and advanced settings.

Remove all inherited permissions. Deny all permissions to SYSTEM and Deny all permissions to Administrators group. Click Apply and OK. Windows will pop a warning about changing permissions on system files and directories. Yes, you want to do this. And that’s it. No registry settings, no firewall rules – just good old NTFS permissions. Since no one can access this folder, it will prevent GWX from installing, even if it’s slipstreamed in a IE update.
