More gremlins, did clean 8.1 install on a rMBP that had been clean installed with 8.1 prior, only difference AFAIK is the recent clean install had the latest boot camp drivers from Feb 11th. This issue wasn't present earlier.
Windows update kept giving me these errors, solution for me was to turn off Defender, change Windows update settings to never check (and leave next 2 check boxes unchecked) and restart. Manually check for updates, and it should work. You may still get the error after subsequent updates, but I would just hit try again and error would not appear.
