User Account Control: Virtualize file and registry write failures to per-user locations
Applies To: Windows Server 2008 R2
The User Account Control: Virtualize file and registry write failures to per-user locations policy setting controls whether application write failures are redirected to defined registry and file system locations. This policy setting mitigates applications that run as administrator and write run-time application data to %ProgramFiles%, %Windir%, %Windir%\system32, or HKLM\Software.
The options are:
Enabled. (Default) Application write failures are redirected at run time to defined user locations for both the file system and registry.
Disabled. Applications that write data to protected locations fail.
