downgrade from w8 pro wmc to w8 pro: regedit hkey local machine => software => microsoft => windows nt => current version export current version reg backup change edition id from "ProfessionalWMC" to just "Professional" run install disk select "upgrade" it should bypass the "unable to downgrade" checker if it's able to complete compliance check if that doesn't fix 100% you may have to delete the "WMC" in the digitalproductid4 binary note: this has taken from somewhere in this forum.
Windows 8 Pro, Spanish language pack. Activated with the gogoCLIENT program and the recommended ipv6 settings until Feb 9th, 2012 Moonrak
Thanks guys finally got it. Used all the instructions above set the DNS. Didn't work at first so used tunnelbroker Set up the tunnel and set the firewall rule. Tried again and beyond my expections it worked. Tried the Go Go thing. But it said it wasn't compatiable with my current windows which was a big deal.
I was able to activate by: Downloaded gogo and tried it but said it needed .NET Framework 2.0 (oh well) Changed dns IPv4 to 8.8.8.8 and 8.8.4.4 slmgr /skms benderrodriguez-1-pt.tunnel.tserv28.waw1.ipv6.he.net slmgr /ato . SUCCESS! ...but then none of the start page apps were working. They each crashed when I tried to use them. . So I reinstalled Windows 8 and now that same technique no longer works. Anyone know what's happening?
tried everything, gogo client is working fine, but always get windows activation error oxc004f074, I'm using Windows 7 Enterprise N
