Assessment Title

Rule Text

The detection of compatibility issues for applications and drivers must be turned off.

Description

Discussion Text

Some features may communicate with the vendor, sending system information or downloading data or components for the feature. Turning off this feature will prevent potentially sensitive information from being sent outside the enterprise and uncontrolled updates to the system.

A standalone PowerShell script to assess this control automatically. Review before running it in your environment.

Syntax-checked as valid PowerShell. Not executed here — running it for real needs the actual ms_windows_2012_and_2012_r2_dc target this check assesses.

# OVAL Definition: oval:mil.disa.fso.windows:def:4484
$registryPath = "HKLM:\Software\Policies\Microsoft\Windows\AppCompat"
$registryName = "DisablePcaUI"
$registryValue = 0

Remediation

Configure the policy value for Computer Configuration -> Administrative Templates -> System -> Troubleshooting and Diagnostics -> Application Compatibility Diagnostics -> "Detect compatibility issues for applications and drivers" to "Disabled".
