Windows 10: Latest security update KB5031356 causes "start icon to not respond. Is this a known issue?

The "start" icon at the bottom left of the lower taskbar stopped working following installation of the latest security update. I have had to uninstall the update to restore functionality to the "start " button--is this a common issue??

Taskbar and Start menu not working after the KB5031356 update failure

My PC just attempted the KB5031356 update released on October 10, 2023. It couldn't be installed due to a problem I've never encountered before, which is listed in the known issues of that update here: https://support.microsoft.com/en-us...045-3570-951fac64-5bf8-4eba-ba18-a9448920df1a. Now, after about 20 minutes of "undoing changes", my PC has restarted, and the taskbar and Start menu no longer work. Clicking on any application icon does nothing, and the Start button doesn't open anything, not even with the Windows key on the keyboard. Only the "Search" function works; the magnifying glass icon works. I've tried restarting File Explorer, a full restart, safe mode restart, sfc /scannow, but nothing has resolved the issue. I've also used PowerShell with admin privileges to run DISM with RestoreHealth, which completed, but the problem persists. On Microsoft's page, it says to reinstall the update after RestoreHealth, but it failed again, getting stuck at 99% and then saying "Couldn't complete the updates. Undoing changes," and we're back to square one with the Start menu problem. Will the Known Issue Rollback (KIR) work, and will a new update be released with a fix? Otherwise, how can this Start menu problem be resolved, which is quite serious and inexplicable (if an update fails, everything should be as it was before; there shouldn't be lingering issues)? What's the purpose of RestoreHealth then?

 

Windows 10 update: start up and sleep issues caused

Dear Vijay,

Thank you for your response: apologies for slow feedback.

Regarding step 1 - doing a restore point : I tried this twice and twice it failed. Now, the date of the update that caused the issue (13/14 September 2019) has disappeared from the history list. Is there a way of finding it, still?

Regarding Step 2- the list of updates installed: the two suggestions above do not seem to appear in the list in the window "Installed Updates".

There are two updates listed for 13 September - Security Update for Adobe Flash Player and Security Update for Microsoft Windows.

Could you advise what I might try next?

Thank you so much.

THE SAME PROBLEM AGAIN:

Updating the driver does not help. But after uninstalling this Microsoft Windows security update KB5031356 - the network adapter works fine again.
