Answer 1

Hi,

There might be some WMI issue in your system.

Please try to run below commands:

cd \windows\system32\wbem
net stop winmgmt
rename Repository Repository.old
net start winmgmt

If issue persists, then please run:
cd \windows\system32\wbem
for /f %s in ('dir /b *.mof *.mfl') do mofcomp %s

If all above cannot resolve the issue, please share a screenshot of the command you are running and the error message.

Thanks,

Sometimes AV restrict running tasklists, so I shall suggest you to uninstall third party AV if any.
