Windows 10: Can I reuse my OEM key on the same PC after resetting?

I'm planning on resting my PC using this method: Start menu>Settings>Update and Security>Reset this PC>Remove files and clean the drive.

I'm wondering if I can still use the same OEM key before the reset. Thanks

reusing windows 10 OEM key on same pc

The OEM key can be reused on the same hardware. It can't be transferred to new/different hardware. A retail key can be transferred to new hardware.,

I'm asking the second thing, if I can reuse my windows 7 key on another machine without any problems. (sorry, I see I forgot to mention it in the original post ^^)

 

windows 7 key reuse

Hey guys,

I'm selling my 1 year old laptop (laptop 2 in sig), which came with Vista OEM.
I installed windows 7 on it with a key from MSDN. My best friend(the buyer) will format the laptop before he gives it to his sister, so I wanted to know how I can reuse my key for a new pc in the future.

I googled a little bit, but I couldn't find a clear answer. Will I have to call Microsoft or something?

kind regards,
