Windows 10: Sept. 2022 preview updates cause shell issues with taskbar, start menu, explorer

Windows[German]Since the rollout of security update KB5018410 from Oct. 11, 2022 (or even through the Sept. 2022 preview update), issues with the taskbar, Start menu, apps and also Windows Explorer can occur under Windows 10 (20H2 to 22H2). Microsoft has just admitted this and has since released at least a partial fix in the form of a Know Issues Rollback (KIR). Here is an overview of this issue.

Various issues since September 2022

Already in September 2022, there seem to have been problems with the shell on Windows 10 after the rollout of an update. But it wasn't until December 16, 2022 that Microsoft admitted to various problems in the Windows 10 Health Status section. In the article Taskbar elements might flicker and causes device instability, it says that the cause is already to be found in the October 2022 update KB5018410 from 11 October 2022, but that it goes back to the preview update from 20 September 2022 (these fixes flow into the security update of the following month):

After installing updates released on or after September 20, 2022, taskbar elements may flicker and cause system instability.

Microsoft described the error symptoms caused by these patches as follows:

  • The weather or news and interest widget or icons flicker in the Windows taskbar.
  • The Windows taskbar becomes unresponsive
  • Windows Explorer stops responding
  • Applications such as Microsoft Word or Excel already open may stop responding w when the problem occurs

Affected are the following Windows 10 clients:

  • ​Windows 10, version 22H2
  • Windows 10, version 21H2
  • Windows 10, version 21H1
  • Windows 10, version 20H2

For Windows 10 version 20H2, only the Enterprise and Education versions are affected, as the Home and Pro versions have fallen out of support. Microsoft wants to provide a solution in one of the upcoming updates, probably in 2023.

Fix via Known Issues Rollback (KIR)

Microsoft now offers a solution via Known Issues Rollback (KIR) for a quick fix. On Home and Pro systems that are not managed, Microsoft automatically rolls out the KIR solution. Since the 48-hour grace period has now expired, the fix should be available on all unmanaged systems. Administrators in enterprise environments with managed updates will need to download and install an MSI installer file with a KIR fix:
