Title

User Account Control must virtualize file and registry write failures to per-user locations. (Cat II impact)

Discussion

User Account Control (UAC) is a security mechanism for limiting the elevation of privileges, including administrative accounts, unless authorized. This setting configures non-UAC-compliant applications to run in virtualized file and registry entries in per-user locations, allowing them to run.

Check Content

UAC requirements are NA on Server Core installations. If the following registry value does not exist or is not configured as specified, this is a finding: Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \Software\Microsoft\Windows\CurrentVersion\Policies\System\ Value Name: EnableVirtualization Value Type: REG_DWORD Value: 1

Fix Text

UAC requirements are NA on Server Core installations. Configure the policy value for Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> Security Options -> "User Account Control: Virtualize file and registry write failures to per-user locations" to "Enabled".
