HighOS hardeningBLWK-WIN-005

User Account Control is disabled

What this means

With UAC off, every program an administrator runs gets full administrator rights silently — a malicious download included.

How to fix it

Set EnableLUA to 1 under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System (or restore the default in Control Panel → User Account Control Settings) and restart.

Check it yourself

Run a scan and look for BLWK-WIN-005 in the results:

bulwark scan

Installed the standalone CLI package instead of the app? The command is bulwarkctl.

How Bulwark decides

Bulwark reads windows_security and reports this check when:

uac_enabled_known == true and uac_enabled == false

If a value can't be read, Bulwark reports the check as undetermined rather than passing it. View the rule source.
