I tried (many times now) to upgrade from Windows 8 to 8.1 using the download from the Windows store. When it asks to restart it comes up with an error saying
Couldn't update to Windows 8.1
Sorry, we couldn't complete the update to Windows 8.1. We've restored your previous version of Windows to this PC.
0xC1900101 - 0x20017
Searching on google for that error I see several people getting that error (although not using vmware) and Microsoft's response is that it is a driver problem. They say to make sure all Windows updates are done (I have done)
Anyone else got this and fixed it?
I'm using Fusion 5.0.3 on a 2012 Macbook Retina
(I have been able to update my Parallels Windows 8 VM on the same machine, but when I import the Parallells 8.1 into Fusion it juts goes into a reboot loop)
I have also got a running 8.1 preview in Fusion.
