Windows 10: Re-install OEM version of W10 Home

A few years back Dec 2015 I bought my laptop with an OEM version of W10 Home and Office Home but in the meantime I have done consulting work for two different companies who each installed W10 Enterprise and Office365; I needed to integrate into their infrastructure. However, I now want to return to my original W10 Home. Is there a way of re-installing my original W10 Home seeing that I don't have any product key or other ID and about 4 years has transpired? My Microsoft account reflects the latest Enterprise version details.

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).

OEM versions of Windows are identical to Full License Retail versions except for the following:

- OEM versions do not offer any free Microsoft direct support from Microsoft support personnel

- OEM licenses are tied to the very first computer you install and activate it on
