Windows 10: Multiple windows on same PC with same license?

I need to use the same license on the same pc, as I need to have multiple versions on windows running on the same computer.

Say one installed normally then multiple virtual machines running on the same pc.

Do I have to purchase multiple licenses or is it possible I use the same license I am using both for the pc and the virtual machine? I will not be using them simultaneously.

Else is there any other way I can have multiple windows on same pc? and shift from one windows to another as necessary.

:)

install oem license multiple time in just one pc

Not a problem reinstalling on Windows 10 OEM on the same machine.

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

- OEM versions allow all hardware upgrades except for an upgrade to a different model motherboard

- OEM versions cannot be used to directly upgrade from an older Windows operating system
