Hello guys. So basically I spent the whole day trying to find a solution to my problem but none of which I found worked for me. While installing SP1 through Windows Update it stops at about 25% and says "Code 490". I downloaded the SP1 iso file to try and install it manually but then I get ERROR_NOT_FOUND(0x80070490). I ran the sfc /scannow and it says that it can't fix the errors, neither can the SFCFix by niemiro. I'm attatching my CBS, my setupapi.dev and the SFCFix log, not sure which ones will be useful. I'd be very grateful if you guys could help me out here :) If I need to give you some more information then just let me know, I'll reply ASAP.
