Windows 8.1 pro + WMC key activation

So it will be fine installing 8.1 pro with a KMS key, then switch to my 8 pro key and it will activate ok?

Maybe a daft question but why can't you just install 8.1 pro with the 8 pro key, or is it different keys for 8 and 8.1? seems silly when 8.1 is a free update anyway.

 

Windows 10 pro product key not activating

Probably should install windows 10 home like you had originally then a phone call to microsoft most likely would activate it - sometimes they want to see a copy of the receipt for the new motherboard.

You might want to try customer support; if you dont have luck running the activate troubleshooter for new hardware.

The new pro key may work on a fresh install, or if you go through the windows store to upgrade to pro and see if your new key works once you have 10home activated.

• You entered a product key that can't be used to activate Windows. Enter a different product key or buy a new product key.
• You upgraded to Windows 10, but the activation servers were busy. If you upgraded from an activated copy ofWindows 7 or Windows 8.1, your copy of Windows 10 will be automatically activated, or you can wait a while and then selectActivate. If you continue to have problems with activation, contact customer support.
• You upgraded to Windows 10 using the free upgrade offer, butWindows 10 isn't activated after a reinstall. Your copy ofWindows 10 should automatically be activated as long as you didn't make any significant hardware changes to your device (such as replacing the motherboard). If you continue to have problems with activation, contact customer support.

Windows 8.1 pro + WMC key activation

This worked for me last time with a Win 8 key.

Install Windows 8.1 and enter KMS key during setup. Once in windows change product key to my Windows 8 key. Go to add features and enter my WMC add-on key. Drink a beer to a job well done.
