Windows 7 Rollups and preventing Updates
The following Windows Update Rollups have recently been made available in the Windows Update utility for Windows 7 SP1 and Windows Server 2008 R2 SP1.
If they are installed, there is a good chance that they will also install the Windows 10-related KBs that were previously hidden in the post Update – preventing Windows 10 upgrade.
After installing any of the Rollup KBs, I would recommend running the uninstallation scripts and following the instructions on that page.
