At first, it always tried to install the updates every time my PC started, but failed and rebooted the PC another time. After a bit of messing around with some of the settings and searching the net for solutions, I'm only left with the Windows Update application telling me: "Windows cannot update important files and services while the system is using them", and prompts me for a reboot which never fixes anything. I've tried many solutions but none of them had worked. From what I saw this forum is quite good at solving problems, so I've decided I'll give it a try. Thanks in advance for any and all help :) PokMadui.
