How to solve the problem that the UAC File Virtualization service in Windows AD failed to start and the driver was blocked from loading? I believe many inexperienced people are at a loss about this. Therefore, this paper summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

Environment

Windows Server 2012 R2

problem

Log error:

The UAC File Virtualization service failed to start. This driver is blocked from loading. Reason

This error usually occurs if UAC is disabled on the server.

If UAC is disabled on the server, we must also disable the luafv service to stop the event ID error about UAC file virtualization.

Workaround disabling luafv service

Open Registry Editor (regedit.exe) and navigate to the following key

HKEY_LOCAL_MACHINE\ SYSTEM\ CurrentControlSet\ Services\ luafv

In the right pane, set the value of the start key to 4.

Then restart the server to take effect.

Warning: when you disable the luafv service, you will lose the IE sandbox mode, the Metro application will no longer run, and you may notice failures in other server components.

If you do disable the UAC service and do not want to receive this alarm, you can no longer receive this alarm after doing so.
