How to block Windows 10 feature updates from downloading

The reboots are caused by a failure of the Local Security Authority Subsystem Service (LSASS) file (lsass.exe), and Microsoft says Windows 10 versions 1809 and newer are now affected.

The business-focused versions of Windows 10 have normally let you avoid major updates for up to a year, which can be helpful if you either value stability at all costs or just don't like change. The image also reveals the new-look Fluent Design icons, which are a little less busy than the previous design.

More information about WUfB and group policies, including Select when Preview builds and Feature Updates are received, can be found in this support document, which includes very helpful examples and illustrations.


There are two ways to achieve this.

Now reboot Windows 10, and the next time you run a scan with Windows Defender, you should (hopefully) find it doesn't misreport these PUAs as still being present. You can now close the Registry Editor and go on with your life without worrying about Windows 10 feature updates. This method also gives you the power to go to the exact version of Windows, and not force upgrade to the latest version of Windows 10.

Enable this policy to specify a Feature Update version to be requested in subsequent scans. Microsoft started the rollout by offering the May update as a manual download for those who clicked the check for updates button in Windows Update. This policy makes sure you stay in the same version until you remove or disable the settings.


Enter 'TargetReleaseVersion' as the name and set its value to 1. The company doesn't recommend updating to version 2004 using other methods when safeguard holds are in place.

Followed by this, you will have to restart the computer. Once installed, it will remain on this version. She added that enterprises in general haven't been keeping pace with Microsoft's OS feature update releases, which arrive twice per year, and they are typically running "versions that I consider to no longer be appropriate".
