Unable to upgrade from Win10 preview build 10547 due to Hyper-V issues


(Pls. read to the end to get the complete story, because the Hyper-V issue did not get fixed as I thought)

For months I tried to upgrade from 10547 to any newer build, but I always had to roll back because 1) The Wifi would no longer work and 2) Hyper-V got stuck on some odd error 0x800700ff, complaining about the extended attributes being incorrect.

I never had the time to fix it, but yesterday, in honor of Valentine’s day, I finally decided to get rid of my ‘friend’, build 10547. After doing all kinds of little tricks to get the Hyper-V working (no success), I finally found this post, leading me to the correct solution: https://social.technet.microsoft.com/Forums/en-US/e57d2fab-4a1c-4d13-bbf9-2704a1c697bc/vms-wont-start-after-updates-and-reboot?forum=winserverhyperv

All I had to do was to go to the two folders mentioned,  C:\Programdata\Microsoft\Windows\Hyper-V and C:\Users\Public\Documents\Hyper-V, and grant myself access to them. Then restart the Hyper-V Virtual Machine Management Service.

The Hyper-V upgrade problem solved, finally 🙂 Or so I thought. Turns out that the fix, or the workaround was actually just to restart the Hyper-V Virtual Machine Management service. So now each time I logon to my computer I have to restart that service – unless the computer had crashed leaving the VMs on, then they would be running already.

Oh, and the Wifi problem was fixed by going to the vendor’s site and downloading the latest Windows 10 Wifi drivers from there 🙂

Btw, 14257 RS1 160131-1800 seems to be crashing my laptop multiple times a day, especially when I work with VS 2015 and RDLC reports (there might not be correlation, but it only crashes when I work on RDLC reports.)

I already tried to opt out of the Insider Program as I need my laptop to work – unfortunately opting out does not really work, but that is another story 😀
