Xbox and OneDrive won´t log in sometimes

For some reason my one computer won´t log on to the Xbox app and OneDrive. My other computer on the other hand works perfectly fine. I can´t seem to find to reason and even tried with a factory reset and still the same issue. Help?

I´ve allready tried deactivating the firewall and even rebooting the computer

 

Vista x64 won't download updates?

The last updates on my home desktop are dated 16th June.
I've powered it on some 3 or 4 times since then, but nothing was downloaded automatically as per settings.

I tried the manual update from the CP but I get an error code 80070002.

I did the troubleshooting suggested (i.e. stop the Windows Update service, delete the temporary update files, restart the Windows Update service, and then try to check for Windows updates again) but I still keep getting the same error code, even after rebooting *Confused

What gives?
