So I was shutting down my Windows 7 laptop and during the shutdown screen it said it was configuring Windows Features and it was stuck at 15%. The weird thing is I didn't change anything in Windows features before shutting down. Since it was stuck at 15% I just did a force shut down. And then upon restarting I get asked if I want to restart in safe mode or just normal windows and I chose normal windows. And then at the welcome screen, it said it was undoing any changes done to the windows features since I forced shutdown. I checked every settings and programs and stuff to see if anything was missing or messed up and everything seems the same as before this incident. Can anyone explain what happened?
