windows 7 pro
 
 
Windows 7 pro to ultimate

Well not sure about premium but I had activation issues and i did the following

1: clean install of windows7
2: try to activate (no joy)
3: ran the following

net stop slsvc
Cd %windir%\ServiceProfiles\NetworkService\AppData\Roaming\Microsoft\SoftwareLicensing
Ren tokens.dat tokens.old
cd %windir%\system32
net start slsvc
slmgr.vbs /rilc

4: rebooted and try activation (again no joy)
5: run windows 7 upgrade from disk
6: tried to activate received wrong serial requires ultimate product key????

I have windows 7 pro... On checking it seems yes my pro is now ultimate and has stopped asking for activation and states it is indeed activated???

no idea how this happened but I am now happy with my new windows 7 OS
