Hey hey,

In need of a bit of help, again. 

Was using my windows 8 based HP laptop earlier today, and it kept bugging me about restarting to install updates and I forgot about it until it forced a reboot and done it on its own. Left it alone and came back to it being off. Pressed the power button and it started up, appeared normal then showed the frown face with error code: OXC000021a

I'm assuming this is something to do with windows update but I can't even boot into any form of safe mode because it just throws up the same error. I have command prompt open now through the advanced startup menus or whatever they're called so could hopefully do something through that though i'm not sure.

I tried this: http://support.microsoft.com/kb/971058 which was linked through another forum to do with the same error code but none of the command lines worked, usually giving "The service name is invalid" error.

Any help appreciated,
Thanks, Sam.
