Assessment Title

Rule Text

Access to Windows Online Troubleshooting Service (WOTS) must be prevented.

Description

Discussion Text

Some features may communicate with the vendor, sending system information or downloading data or components for the feature. Turning off this capability will prevent potentially sensitive information from being sent outside the enterprise and uncontrolled updates to the system. This setting prevents users from searching troubleshooting content on Microsoft servers. Only local content will be available.

How this relates to the STIG checklist: STIG vs SCAP benchmark.

Remediation

Configure the policy value for Computer Configuration -> Administrative Templates -> System -> Troubleshooting and Diagnostics -> Scripted Diagnostics -> "Troubleshooting: Allow users to access online troubleshooting content on Microsoft servers from the Troubleshooting Control Panel (via the Windows Online Troubleshooting Service - WOTS)" to "Disabled".
