Vulnerability 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

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

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".
