If that does not work then unplug all USB devices.
I keep getting error code 0x80070020
I have rebooted several times and disabled all firewalls. I tried booting in safe mode but couldn't get access to the "store."
Any suggestions? I have a fully updated SP with pretty standard programs installed (Office, PDF annotator, etc.).
after upgrading mine sp kept crashing over and over so I finally gave up did a factory reset and tried again...I did lose all my data but that was being synced via dropbox so i really did not care. Just be sure to remove your store activation first...seems more stable now but still cant get miracast to work.
FWIW IMO These events are not unique to Microsoft. I know personally because I have used all of the other major OS's with similar experiences.In the end I had to refresh windows and lose all my applications. What a pain. I've just spent an hour trying to get the Wedge Mouse to pair, without success.
Microsoft is still Microsoft.
