It's a ready VM from NHC, normal Win7, not tiny, I downloaded it like 3-4 months ago. I have had errors (that blackscreen) on it before, so I downloaded shadowlink's VM 1-2 months ago, thought it will be stable and expected better performance, but no, it was worse, more black screens and VMs restarting themself. I went back to NHCs version to check if it's going to work now and it does, very well atm, installed everything from the beginning.
