My pc did some updates yesterday and after reboot, it is stuck at "preparing to configure windows do not turn off computer" It was like this for about 2 hours, so I reboot it. Every time I boot my pc, it says the same preparing to configure..... and stays there forever. I tried to safe mode, nothing. I tried to restore to previous state, but I had it disabled. I left it like this over the night, but in morning, it was still in this preparing.... Please some help. Thanks.
