Even if you convert the hard disk image to a different format and run it on VMWare/VirtualBox/whatever, it won't do you any good. Due to the substantial change in hardware that Windows would see, the system would not be activated.
Nah, it's just for testing things, KMSMicro itself is good to activate win8.1 & Office, if people works on the VHD, he can covert it back to kmsmicro.ron to replace the original file in KMSmicro.
Sure. For example, to export files from KMSmicro. I was answering Garbellano with my comment that a VHD won't do you good, I didn't mean it as a response to the OP. Sorry for the confusion, I should have used quote.
