The User Account Control: Virtualize file and registry write failures to per-user locations setting should be configured correctly. This 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. Fix: (1) GPO: Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options\User Account Control: Virtualize file and registry write failures to per-user locations (2) KEY: HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System\EnableVirtualization
