Overview​

This script disables privacy mode for Defender scans, limiting threat history access to administrators.

By default, privacy mode is enabled 1. When active, it restricts the display of spyware and potentially dangerous programs to administrators only, instead of all users on the computer 2. It blocks non-administrators from viewing threat history 1.

This is a legacy setting that only affects older versions of Defender Antivirus 1. It has no impact on current platforms 1.

Limiting threat history to administrators has both benefits and drawbacks. It improves security and privacy by limiting access to sensitive threat information. However, it may reduce transparency and hinder security efforts for users without admin access who need this data.

Caution

Non-admin users will be unable to view potential security threats on their accounts.

Technical Details​

The script configures:

  • DisablePrivacyMode Defender preference using Command Line Interface (CLI) 1 3. It sets the value to $True, effectively disabling privacy mode 1.
  • HKLM\SOFTWARE\Microsoft\Windows Defender\UX Configuration!DisablePrivacyMode registry value 2. This undocumented registry key has been verified to work on older Windows versions by the community 2.
