Windows 10: Reinstall Win10 with old OEM key.

My windows 10 has been acting funny for a while, its running on an ssd but still feels sluggish. I'm hoping a fresh windows install and drivers will help it feel brand new again.

My question is, can I use my current key again? I have an OEM key which has been activated. Is it possible to re use the key?

Upgrading OEM Win10 Home to MSDN Win10 Pro

Moving to a new PC that I'm building myself. Currently running Dell OEM Win10 Home. New PC will have Win10 Pro, MSDN (multi-activation or retail keys) version.


My backup software can do a "system transfer" that will allow me to transfer everything (OS and applications) to the new computer.


Should I upgrade from OEM Home to MSDN Pro on the old computer and then transfer everything to the new computer?


Or just install Win10 PRO MSDN on the new computer and use the backup software vendor's application transfer program to move the applications and registry entries?


My goals are:

1. Not have any "dinosaur bones" either from the OS on my SSD from the old OEM Home version on the new PRO version

1. Not have to reinstall and reconfigure everything (which would take about a week)

Thanks for any advice I can get...

Asked for a Win10 activation key when I updated from my Win7 Pro OEM

You have to reinstall your Win7 OEM and upgrade to Win10 from your old windows.

Good luck.

p/s: After upgraded to Win10 and active it, you can do a clean install without product key.
