This morning it was working perfectly fine and when I turned it off, it said that it had some updates so I turned off the screen so that it could update and turn itself off when it was done. I come back in the afternoon and when I turn it on, it says "Preparing to configure windows" and it takes a long time and eventually says "Failure to update windows" and resets itself. The second time, it also says "Preparing to configure windows", but then it says "Failure to update windows, Reverting changes". It then lets me get onto my desktop, but everything that I downloaded from the internet has an Application Error (0xc0000005) and it won't open: iTunes, Google Chrome, Microsoft Word, etc. I can open any files on my computer just fine.

I tried doing a system restore to the time that I turned off my computer this morning but it said that it didn't go through. I tried another one that was a few days ago, but it didn't go through either and said something about the shadow of the copy not completing. Any ideas on what to do?

A quick google of the error code indicates that there are a variety of reasons this could occur. Given that it happened during an update I'm assuming you now have a corrupt installation, could be the registry a driver or something else. If you have the original Windows disc try a repair/restoration from the disc. Your probably also going to have to reinstall everything else.

That is defenetely one way of fixing it.
It could also be a security/access rights issue.
Notepad, paint and some other apps do start.
Safe mode doesn't help, so it's likely not a driver.
Also, I get access error when trying to roll back to the older restore point.

Wonder if disabling DEP might help but apparently it could lock you out.

I managed to uninstall the hot-fixes and system is working now. Couldn't do it from within the OS though.
Here is what I did:
- Run windows install disk
- select repair instead of Install
- now you need to get to this screen and select last option

There will be a tool for uninstalling hotfixes, have to go through and find them as they are not sortable by date.
Good luck.
