I agree! Hopefully we can get a working patch soon, however it seems things have change a lot in win2k12 since its taking a bit to get a working patch. It is likely that this will be solve once the OEM start shipping out.
Cannot insert key, as I get always an error like I should run on a computer with windows (no core-edition) slui.exe. Besides I don't know which key of these "Windows 8 KMS Client Keys" on pastebin to use.
use the key that it came with during install. there is no need to change the key. just open the command prompt as admin and type Code: slmgr.vbs /skms 147.134.1.42 then Code: slmgr.vbs /ato then Code: slmgr.vbs /ckms After each you will get a prompt, first one should be successfully changed kms server, second should say activated, third should say cleared kms server.
For some reason I am having problems activating Windows Server 2012. I can activate Windows 8, but not Windows Server 2012. The message I get when I am trying to activate: I can ping the KMS from the machine, so it's definately reachable.
