Key Developments & Data
Microsoft has acknowledged a bug in Windows 11 where the system falsely alerts users that Microsoft Defender Antivirus is turned off.
The issue specifically affects Windows 11 version 25H2 and was officially logged by the company on August 28th.
These erroneous notifications trigger upon startup and intermittently afterward, entirely bypassing standard user notification settings.
Despite the persistent warnings, the actual antivirus software remains fully functional and system protection is not compromised.
Users are advised to manually check their security settings to confirm Defender is active while waiting for a software patch.
