Microsoft has confirmed that notifications stating “Microsoft Defender Antivirus is turned off” are erroneous and can appear during startup and intermittently, even with notification settings disabled. The issue stems from recent updates to Windows antivirus software, but the antivirus is functioning correctly. This problem affects all versions of Windows or Windows Server running Microsoft Defender Antivirus with the latest updates. Users may see pop-ups urging them to “Turn on virus protection,” which falsely suggest that protection is disabled. Microsoft is working on a resolution, and users are advised to verify that their antivirus is operational and that real-time protection is enabled.

Microsoft's optional update for Windows 11, KB5120998, is causing issues with mouse cursor settings, reverting them to default configurations after installation. Users are experiencing frustrations as personalized cursors are replaced by an oversized default version, and adjustments to color and size often do not persist. This problem appears to be linked to specific hardware configurations or display scaling setups. Microsoft is investigating the issue, and users can uninstall the update to resolve the problem without affecting access to essential security patches.

Microsoft will implement changes to Windows PC updates next month, requiring mandatory restarts for specific security component fixes in September and October. The September update will necessitate a "force restart," while the October update will follow the regular quarterly routine. These changes primarily affect managed PCs, and IT administrators are advised to inform users. Additionally, users are cautioned about the Windows 11 update KB5120998 due to issues like broken cursor styling and reset wallpaper settings, with some users successfully resolving problems by uninstalling the update. Windows 11 users are also experiencing a DISM error, 0x800f0915, when repairing the system image post-update, although reports of this issue are low.

Windows updates are released frequently to enhance performance, improve compatibility, fix bugs, and distribute critical security patches. Microsoft issues security updates every second Tuesday of the month, known as Patch Tuesday, which are cumulative, meaning the latest updates include all previous fixes. The Cybersecurity and Infrastructure Security Agency (CISA) issues warnings about vulnerabilities, and Microsoft maintains a security portal for documentation of these issues. Users on unsupported versions, like Windows 10 without Extended Security Updates (ESU), are at increased risk. In addition to security updates, Windows receives an annual feature update and occasional optional non-security updates that introduce new features and enhancements. An example is the Windows 11 February 2026 preview update, which added new features and improvements.
