Windows 10: Task manager works strange

Everytime when i I turn on the computer, I always enter Ctrl-Shift-Esc, to open task manager, but now, two days ago and still opens a dialog "Do you want to allow this app to make changes to your device?" should i be concerned or it's nothing serious ?

No restart button in task manager

another easy way to kill tasks, download and install Winaero Tweaker(free) and theres a setting to add a Kill non responding tasks using the desktop right click menu. When you place your cursor on the desktop anywhere and right click the option is at the top of the list, Very handy and you dont have to go through all those steps and well Winaero Tweaker has alot of cool Windows tweaks. Just posting a different suggestion, Im sure your ok with what was suggested here.

 

Task Manager not working


Topguncp - I went into Admin Command prompt and followed your three steps which fixed the problem Task Manager now working. Thanks for your assistance. Cheers

 

Task Bar, Task manager and apps, all not responding, Windows 10

step 1 worked a dream. Had earlier tried everything suggested in these forums. nothing had worked to solve the problem. The media creation tool as suggested in step 1 did the trick. - it took several hours, but worth it.

ps. original complaint - non responding - and task manager - blank or useless.
