Title

User Account Control must only elevate UIAccess applications that are installed in secure locations.

Control

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: EnableSecureUIAPaths Value Type: REG_DWORD Value: 1

Discussion

User Account Control (UAC) is a security mechanism for limiting the elevation of privileges, including administrative accounts, unless authorized. This setting configures Windows to only allow applications installed in a secure location on the file system, such as the Program Files or the Windows\System32 folders, to run with elevated privileges.
