For some reason the initial update hung up at the 58% mark and I had to restart the vm where the number of items dropped a bit. Since the restart however the WU seems to have sprung back to life a bit and once the 14295 is on that the other Home and Pro VMs are next in line.

First however I will need to expand the VHD since that ran out of space a bit too soon! Since the upgrade from BT folder worked out I will first back that up on the host drive or second drive's backup partition being the larger there and then clear off some other stuff now that 10 is on over the 7 vm. If I cut that from 60gb used down to 25gb that should work out.
