On the 2nd September I put together an Win 8.1 Pro WMC iso using the instructions posted on this site. Win 8.1 WMC Create activate the Windows 8.1 Professional with Media Center using you free Media Center key iso used -> MICROSOFT.WINDOWS.8.1.RTM.X64.ENGLISH.DVD-WZT. extract install.wim your iso. perform the following procedure in CMD. dism /mount-image /imagefile:e:\install.wim /index:1 /mountdir:e:\mount Dism /Image:e:\mount /enable-feature /featurename:NetFx3 /All /Source:k:\sources\sxs /LimitAccess dism /image:e:\mount /set-editionrofessionalWMC copy e:\tokens.dat e:\mount\Windows\System32\spp\store\2.0 /y copy e:\data.dat e:\mount\Windows\System32\spp\store\2.0 /y dism /image:E:\mount /set-productkey: (using you free Media Center key) dism /unmount-image /mountdir:e:\mount /commit add file ei.cfg to sources in your iso. This allowed me to reinstall Win 8.1 Pro WMC on the machine that product key was licenced to. Yesterday I inserted KMSpico's latest "OEM" folder into the "Sources" folder of my iso. I installed it on 3 different physical Machines (not VM). All are activated, installed Office 2013 Pro, restarted machine, Office now activated. When I checked the product key it was not my original WMC key. Effectively I now have a KMS activated Win 8.1 Pro WMC iso that will instal on any PC. Thankyou to Heldigard for KMSpico and Murphy for iso creation. Hope this helps those who have been looking for a way to activate Win 8.1 Pro WMC using KMS.
If i want include completely GA Rollup-1 in this ISO image, what I have to do? Activation also will works?
I did not find it necessary. To make this iso you have to start with a legitimate Win 8.1 Pro WMC. In the script you will notice the lines: copy e:\tokens.dat e:\mount\Windows\System32\spp\store\2.0 /y copy e:\data.dat e:\mount\Windows\System32\spp\store\2.0 /y dism /image:E:\mount /set-productkey: (using you free Media Center key) these are the tokens+data and legitimate product key from an existing activated installation of Win 8.1 Pro WMC. The resulting iso is used as a backup for re-installation on the same machine (will not activate on any other machine). The later addition of KMSpico's "OEM" folder injected into the iso using PowerISO is what enables the reconstituted iso to be installed and automatically activated on any other machine
