To enable concurrent logins into Windows 8 (I needed this for VM testing for all my engineers, as I do not want to create 6 VM's nor roll out 6 test PC's), you need to do a couple of things. I used a directory on the Desktop to do all the work...) 1. Get yourself a HEX editor. I found a pendrive program called HEX-ED at: ww<dot>pendriveapps<dot>com/hex-ed-portable-hex-editor/ 2.
