Well upgraded from 10159 to 10162 with now obvious issues. Took less than 20 mins. Will post any issues as I find them.
Download goes to %windir%\SoftwareDistribution\Download\ then file gets decrypted and converted to $Windows~BT folder.
Really? My 10159 stuck at 0% as usual. This time I just left it alone and kept watching C:\. Yes, $Windows~BT was there. And finally it started to install.
