In a surprising turn of events, Windows 10 users are encountering new bugs as the operating system approaches its end of support, scheduled for less than a year from now. Microsoft has acknowledged the emergence of at least three issues affecting users who installed the recent updates, specifically KB5044273, released during the mandatory October Patch Tuesday, and KB5045594, an optional patch made available on October 22.
For some, the installation process itself has proven troublesome, with error codes such as 0x800f0805 hindering progress. Meanwhile, those who successfully installed either update have reported significant challenges, including applications failing to launch altogether.
One user shared their experience on the Feedback Hub, detailing how their Lenovo 20WE computers struggled to open applications post-installation of the KB5044273 security update. “We are having issues opening applications after applying KB5044273 on all Lenovo 20WE computers. The issue resolves after uninstalling the update,” they noted, highlighting a workaround that involves reverting the update.
Another user reported that their apps, including Wallpaper Engine and TranslucentTB, failed to start automatically upon logging into Windows after the update. This bug is particularly concerning as it affects users outside the Windows Insider Program, indicating that even those on officially supported hardware are not immune to these issues.

In a recent update to its support documentation, Microsoft confirmed that several applications, including Teams, Narrator, and Quick Assist, may crash when accessed by non-administrator users. While the exact number of affected apps and users remains undisclosed, the prevalence of the issue has prompted Microsoft to consider an emergency patch.
Microsoft has indicated that the crashing issue is likely to occur when applications are set to launch with non-admin rights using the UIAccess=true setting. This affects applications located in the following directories:
- %ProgramFiles%
- %ProgramFiles(x86)%
- %systemroot%system32
- %systemroot%syswow64
However, running applications with admin rights does not guarantee immunity from crashes. According to Microsoft, while users may encounter fewer issues when operating as administrators, problems can still arise.
The second bug identified in Windows 10 KB5044273 primarily impacts enterprise customers utilizing Azure Virtual Desktop (AVD). Users may experience a black screen upon login, with the possibility of being unable to log out, leading to further complications when attempting to access AVD again. Those affected might notice ‘svchost.exe_AppXSvc’ in the Event Viewer, and this issue can also result in the Start menu crashing or closing unexpectedly.
The third significant issue presents yet another black screen, lasting anywhere from 10 to 30 minutes during the login process to Azure Virtual Desktop (AVD).
Microsoft is actively working on solutions to these bugs, with expectations for fixes to be rolled out on November 12, coinciding with the Windows 10 November 2024 Patch Tuesday refresh. Additionally, the company has announced a option for users wishing to extend security updates for Windows 10 for an additional year, pushing the end of support to October 14, 2026, instead of the original date of October 14, 2025.
