I had to reinstall windows 8 due to it not booting and being sluggish once its booted. I followed instruction on the restoration of keys using JaguarXJ12 method. After following it, I could not get it to activate as my store folder was backup with WMC. I was wondering how can I install back WMC to the current Windows 8 I'm using. My Windows 8 Pro + WMC is activated during the early days with the WMC key glitch that fully upgrade it into windows 8 pro + WMC. I hope I can get some advice thanks.
