I just finished installing Windows 8 Pro x64 RTM and I'm in the middle of activating KMS. I got my free WMC in just less than 5 hours. I'm following this procedure for activating KMS: 1). Activate your copy of windows with a MAK or KMS method 2). To activate windows using KMS server, run Command Prompt (CMD) as Admin and enter the following in the given order: slmgr /ipk -J8CK4 slmgr /skms 126.96.36.199:1688 slmgr.vbs -ato slmgr /ckms If the server is running then you will be activated for 180 days. I can't seem to activate it using this command: slmgr /skms 188.8.131.52:1688. Can somebody please link me to a working KMS server. Please help me out. I'm new to this thread and I promise I have done a lot of reading. But I'm getting a bit confused what to do next. Please help! Thanks in advance!
