I am about to give up on Parallels now. I do not have any idea of how many times the Windows installation on my Mac has turned into a mess of "needs to repair", Errors, all apps dissapeared when starting the virtual machine. One day everything works perfectly, the nest time I start, it does not work. It is such a hassle. Like this: I had a perfectly running windows vm running. For weeks. Suddenly one day when starting up, it just went into a loop of repairing, restarting, repairing, missing boot-files etc. So I restored a copy from Times Machine, this one worked for a week, then ALLE apps where gone from windows 8.1. It seemed to have deleted the old user and recreated a new one. May be it is Windows which suddenly decides to scrap my old user and make it new. With the same name, but whit all apps gone. So, I try to reinstall the latest working version of the vm from Time Machine again, but this time ir will not work at all. So, the same version that just worked the last time I restored it, will not work at all, only blue screen. Must also say: before the "perfectly running windows vm", I have had lots of trouble, even a parallels support person had to help, and struggled with reinstallation's etc. The strange thing is, one day it works, and the next day is does not work. For example, one time I did the "space reclaim", but should not have done that. The vm went crazy and I had to reinstall. Now I am tired and fed up with parallels! When writing this, my windows screen is dark blue, and nothing works.
