First, backup what you can't lose to DROPBOX, USB sticks or anywhere but this PC. The WPD message was noted back in Vista days where a security update whacked some WPD drivers that were not well written but let's move on to trying Grif's hunt for malware.

Hi, I am in middle of end of term coursework exams and my computer is unstable! I have Win 7, and have had problems since trying to install Service Pack 1 about 2 months ago. Basically it won't install. I tried everything recommended by Microsoft and other forum postings, but nothing worked. I can't get past 8% when it restarts, it hangs all night. So I have to manually restart and then it reverts back and undoes the install. I had to leave it like this as I had work to do and it seems to work ok, albeit a bit slow. All was OK until this week when my external harddrive could not be recognised. I frantically tried to do a backup on another harddrive but I got a bluescreen with long message which disappears quickly on reboot, saying there is a problem with "the driver or WPD filesystem volume driver. Now I can only use my computer in Repair Mode/Safe Mode, which is what I am in writing this. If the computer starts normally I get the crash and bluescreen. I have followed advice to reinstall device drives and in device manager the WPD devices have alerts, but un-and reinstalling each device makes no difference. I have nothing connected to the PC now, the drives are showing but when I connect something it is not recognised. I thought it was related to Service Pack 1 so spent ages on trying to figure that out again, renamed software distribution folder and other stuff as advised (and eventually as last resort downloaded manually (oh, windows update does not work) the service pack 1, burned to a DVD, but just had the same result with hanging at 8% on restart.
I know I am going on, and I hope I am making sense, but I have spent 3 days trying to do this by myself with advice from the internet and now am at a loss as nothing seems to work. I can't remember everything I have done/changed, but if someone mentions it I can say if I've already tried that! I can attach a log which I generated that lists all the exception codes, windows error messages and something 'bucket' code that was suggested? if that's any help to someone? I hope someone likes a challenge - I do usually, but I have exhausted everything suggested that should fix it.....
