Windows 10 Start Menu & other issues

[Qui-Gon John]

I was helping someone today and I did a cleanup on Windows 10. After this, when it booted back to normal mode it had the following weird symptoms. If I click on the Start Menu icon or press the Windows Key on the keyboard, nothing happens. If I try to type in the search box, it does not type. I cannot right-click any icons in the taskbar (left hand side) to "Unpin from Taskbar" or do anything else on that menu. If I right-click on the Start Menu icon, I DO get the normal menu there. I tried a System Restore but that was unsuccessful. I Googled repairing the Start Menu, it said to launch "sfc /scannow" in Powershell. Since I could not access Powershell by typing the command into the Search Box, I did this from Task Manager. It opened, but would not let me run the sfc unless I had an elevated Powershell (which normally I type it in the Search Box and when the result comes up I right-click and say "run as administator"). I cannot do that from inside Task Manager and was unable to run Powershell as Administrator.

Any help of fixing these issues would be appreciated.

Seems like some system files/drivers were corrupted by malware.. Why can't you start elevated powershell/command prompt and run the repair commands from there? You may have to reinstall the OS in place, ultimately if nothing else helps.

I don't know how to start Powershell in elevated "run as administrator" any other way than typing POWERSHELL in the SEARCH BOX, then right-clicking the result and selecting RUN AS ADMINISTATOR. Since the computer is not taking any typing in the Search Box, I seem stuck. I can press Windows + R but if I type POWERSHELL there, I see no way to RUN AS ADMINISTRATOR. Is there a switch I can use in the Windows/R box, like powershell /A (just guessing about a letter for that. Or any other way to get Powershell to Run As Administrator.

Task Manager > New Task > powershell and check run as admin, click ok.

I did not see a box to check there, for Run As Admin, but I will look again. Thanks!

I took another look and did see the check box beneath where you type the command. Not sure how I missed it first go round. I did check and that is NOT there in Windows 7.

Will give this a try next time I see that person.
