How can I DE

:)

 

My pc takes for ever to shut down when i restart

Suggest cleaning up your startup list .There may be many services / Apps you can remove on startup which is not needed on boot or during shutdown.
Before you shutdown the Pc check what is running in Task Manager as a program or service in not killing the process on shutdown

Would suggest cleaning up running apps and services -Autoruns, StartupMonitor,HighjackThis,
Malware Scan - Malwarebytes,ADWcleaner, Combofix

Program Manager Hangs On Shutdown

Thank you, I had planned to follow these steps today, but now I think I've figured it out. Ever since I performed a DDU clean install of my GTX 1060's drivers, updating them from 388.71 to 390.65 yesterday.
Program Manger, whatever it was, no longer hangs on shutdown. In it's place,
NvFBCPluginWindow hangs in the exact same way. I always do a clean install of my Display Drivers, uninstalling with Display Driver Uninstaller in Safe Mode, then disconnecting my Ethernet entirely before installing the latest drivers
from a USB stick to prevent Windows from trying to install them at the same time. So I guess until Program Manager starts to hang again I'll continue this discussion on the GeForce forums. If it does reoccur I'll immediately follow your linked steps & report
back my findings. It's my suspicion that Program Manager was/is related to Nvidia or it was just falsely identified by Windows 10 & was their Plugin Window task hanging all along.
