Determining registered Windows 10 version from computer with removed HDD

[Admetos]

I've been given an AMD 6 core PC, for security it's had it's HDD removed.

I presume it's had Windows 10 on the machine previous. I want to install Windows 10 on the PC again, is there anyway of detected what version of Windows 10 would have been registered to it?

Thanks for everyone's reply's, will try both both versions of Windows, and hope that one registers.

Install Home then check activation. If not activated run troubleshooter. Windows will tell you if it finds there's a licence for 10 Pro and if so will download the necessary files to upgrade the installation.

Thank you so much for that information , will try above!
