Solved! Task Manager not working on Lenovo Notebook


Since the last two CIS Updates the task manager didn’t work anymore on my Lenovo Notebook, WIN7 64Bit.
When I tried to open it, it instantly closed again. Same issue with Killswitch and WinRar for example.

Thanks to Sysinternals ProcMon I managed to find out what is causing this problem:

It is Lenovo OneKey Theater!!

I uninstalled it and now everything is working fine!

Hope this is useful for you guys!


Thanks so much for sharing the solution! I spent all weekend searching for a “virus” causing these problems, even reinstalled the system in the process :smiley:
