Start10 + Start11 - Click on start button problem

Hello,
Sorry to hear you are having issues. But, I can not reproduce your issue. Refer my short video below.

Also,

I suspect, this show that the issue is not from Start10. Perhaps try system scan.

Please try the following:

-For Win8/10 Users: Open the Start Screen, and type 'cmd'. Right-click on the search result and select 'Run as administrator' from below.

-Type: sfc /scannow

-Wait for the scan to complete (this can take several minutes)

If the SFC finds errors, but cannot fix them, please also run the following command in the same command prompt window:

dism.exe /online /Cleanup-Image /RestoreHealth

The above command should assist with replacing any damaged or problematic system files. Please note, however, since it may require restoring certain files, this process can take some time and you will need to be patient until it has completed.

Please let me know whether this resolves your problem or if you have any additional questions.

Thank you,

errors found, SFC corrects them.

i used also DISM.

restart.

Same thing.

Maybe it's asking for an OS reinstall.
