2/3 successful W10 upgrades. The 3rd was suckfest full.

 Scheduling your upgrade is stoooooooopid since you are limited to 3 days.  I want to wait til July 28,2016 on a new build. What happened is most apps would not open. No browser could open. I didn't check the DAWs buy Live opened with no problems. Start Menu would not open right away.   I had internet but all broken browsers, even Edge.  Many utilities wouldn't work. This machine is a little over 2 months old so it really can't be blamed on software since my old legacy Intel machine is running the same software.
 A clean install should work but Windows 7 is getting hard to part with concerning two machines that are new builds. BTW the roll back was successful.
