Microsoft: Windows updates make password login option invisible

Microsoft has warned Windows 11 users about an issue where the password sign-in option may not appear on the lock screen after updates since August 2025, although the functionality is still available.

Microsoft is working on a fix but has not provided a timeline. Additionally, Microsoft addressed other issues related to the KB5064081 update, including playback interruptions in DRM-protected video applications and installation problems for non-admin users.

Tested: The Task Manager bug that slowed your PC is gone in Windows 11 Build 26200.7171

Microsoft has released the Windows 11 November 2025 Update (Build 26200.7171/26100.7171 or newer), which fixes an issue where the Task Manager did not close properly when the Close (X) button was clicked. This problem, first observed after the October optional update (KB5067036), caused multiple invisible instances of the Task Manager to accumulate, consuming 20-25 MB of RAM and 0 to 1.5% of CPU resources, leading to performance degradation. Microsoft confirmed that the October update inadvertently caused this issue while attempting to fix a grouping problem within the Task Manager. The November update (KB5068861) resolves the bug, restoring the expected functionality of the Task Manager. Users can check for lingering instances by opening the Task Manager and observing if multiple instances appear after closing and reopening it.

Microsoft: Patch for WSUS flaw disabled Windows Server hotpatching

An out-of-band security update, KB5070881, has disrupted the hotpatching feature for some Windows Server 2025 devices. This update was released alongside reports of the CVE-2025-59287 remote code execution vulnerability. The Cybersecurity and Infrastructure Security Agency (CISA) has instructed U.S. government agencies to strengthen their systems against this vulnerability. Microsoft has acknowledged that the OOB update caused some Hotpatch-enrolled Windows Server 2025 systems to lose their enrollment status and has ceased distributing the update to these devices. Those who installed the update will not receive Hotpatch updates in November and December but will get standard monthly security updates. Administrators can install the KB5070893 security update to address the CVE-2025-59287 flaw without disrupting hotpatching. Microsoft has also disabled the display of synchronization error details in its WSUS error reporting system and resolved various issues affecting Windows 11.

Microsoft: Windows Task Manager won’t quit after KB5067036 update

Microsoft has acknowledged an issue affecting Windows 11 users after installing the optional October 2025 update (KB5067036), where the Task Manager does not fully close when the "Close" button is used, resulting in multiple instances of taskmgr.exe running in the background. This can lead to performance degradation, including system stuttering and CPU hangs. A temporary workaround involves manually terminating each Task Manager process or using the Command Prompt with the command: taskkill.exe /im taskmgr.exe /f. The KB5067036 update also introduced enhancements like an updated Start Menu and restored functionality to the Windows 11 Media Creation Tool, while addressing specific update errors.

“Update and shut down” no longer restarts PC, as Windows 11 25H2 patch addresses a decades-old bug

Windows 11 25H2 Build 26200.7019 and 24H2 Build 26100.7019 have resolved the issue with the “Update and shut down” feature, which previously led to unexpected restarts instead of shutting down.

The optional update released in October 2025 (KB5067036) addresses the problem that prevented “Update and shut down” from functioning correctly. Microsoft confirmed that the update rectifies the underlying issue causing the feature to malfunction.

‘Update And Shut Down’—Microsoft Confirms Windows Update Mistake

Microsoft has acknowledged a significant update error affecting Windows 10 and Windows 11 users and has rolled out a fix. The fix addresses a problem where selecting “update and shut down” would trigger an “update and restart.” This issue has been described as a “decades-old bug” and has been particularly frustrating for laptop users. The October 2025 optional update (KB5067036) resolves this issue. Additionally, Microsoft is simplifying the update process by introducing more user-friendly names for updates, eliminating unnecessary technical jargon while retaining essential identifiers. However, a long-standing driver error (0x80070103) in Windows 11 remains unresolved, with a patch aimed at alleviating the problem but no complete fix currently available. Users may still encounter difficulties when installing a driver that is already present on their PC.
