Here’s the light of highlights for the optional KB5005611 patch that Microsoft mentioned on its Windows Support site:
- Updates an issue that causes the system clock to be wrong by one hour after a daylight saving time (DST) change.
- Updates an issue that causes applications, such as Microsoft Outlook, to suddenly stop working during normal use.
- Updates an issue with the Microsoft Outlook Add-in that prevents you from typing a reply.
- Updates an issue that causes blurry News and interests icons when you use certain screen resolutions.
- Updates an issue that causes News and interests to appear when you right-click the taskbar even if you have turned off that feature on your device.
- Updates an issue that might cause distortion in the sound that Cortana and other voice assistants record.
- Updates an issue that causes your device to stop working after you restart it.
- Updates an issue that prevents you from providing input to apps when the taskbar is not at the bottom of the screen.
As usual, Windows 10 users who prefer to skip this optional patch will still get all these fixes when installing next month's Patch Tuesday update, which will be released on October 12. Microsoft is also getting ready to release Windows 10 version 21H2, the next version of the OS for users who won't be able to upgrade to Windows 11 for free. The software giant has yet to announce when Windows 10 version 21H2 will start rolling out, but it will likely follow the official release of Windows 11 on October 5.
