I recently upgraded Windows 8.1 to Windows 10. I found that Windows 10 App Store,Xbox,Windows Update not working but other apps like News, Weather works.
I tried Windows App troubleshooter, Windows Update Diagnostic. Preliminary results show that "Service Registration is missing or Corrupt". I tried refreshing PC but didn't work..
