Just following the three steps:

1. Install Win8 pro version;not Pro vl version,this is very important;
2. When you finished 1; the system should be Windows 8 pro version; if you intall Windows 8 standard version, never mind, upgrade to pro version by Pro version CDKEY. After that, you need to activate system by KMS(6 months).
3. Apply for WMC CDKEY, and install WMC;the system will automatic restart;
4. When finished 3; the system should be permanent activation.

简单说··就是利用WMC的CDKEY来进行激活··但是只可以激活专业版·VL的专业版和企业版都不可以·
