Windows 10: related to OEM key

Hi experts, i need to know that can i use my OEM key again in my computer?my preinstalled windows 10 HOME enabled with OEM key got crashed, so i took my laptop to service center they installed a new version of windows 10 enterprise with KMS server and i know that it is not legal to use KMS server as a home usable system.

Question On OEM Windows clean install......

"Flavors" of Windows licenses

Windows can be a little "odd" about license keys. There are at least 4 categories:

• Retail
• OEM
• Volume (electronic download)
• Corporate (no key needed)

For guaranteed success, the license key and media should be in the same category. If you have retail media, you may not be able to install it using an OEM or Volume license key, even though the key is valid for that version of Windows. *Wtf :wtf: Apparently, this is part of Microsoft's anti-piracy scheme (i.e., all customers are guilty until proven innocent).
