See my other posting Activation error 0xC004F074 and 4 ways that don't fix it
It keeps saying Windows 8 is not activated, and No Key Management Service could be contacted after 6 month with no problems.
Bought a used HP laptop that originally had Win7 Ultimate, and the previous owner had split the hard drive into two partitions and put Win8 Pro on the second partition. The boot up process is controlled by Win8 and you select at startup whether you want to go to Win7 or Win8. Pretty neat. BUT...
4.) Obtain a genuine key for Windows 8 Pro ... (PS don't forget to find the guy you bought it from and kick his ass...!)
Will an OEM license from TigerDirect work OK?
Activation error 0xC004F074 and 4 ways that don't fix it
OK, bought a used laptop with dual boot Win7x64 / Win8Prox64 in Feb. 2013. Win8 booted up and ran just fine for the first six months. I don't know if it had anything to do with it, but I installed Office 13 in the Win8 partition not long...
