Windows 10 pro key? Second hand?

I just reinstalled Windows on my laptop.

I still have the old Windows 10 pro key and wanted to activate it, but according to the Internet a 10 needs more performance and is not ideal for gamers.

I bought earlier because I thought the home version was a demo.

Well, I don't do much with it except gamble or program (I'm just trying) and discover software.

Should I activate it or not?

If not, can I sell it?

I'm sorry about my grammar and spelling mistakes.

You can sell it, but many people are afraid that you are selling used or fake software. As far as I know, the Pro version is not much more performance-intensive, but if this little extra power is important to you, you have to get the home version

Windows 10 Pro is made for the office and is not recommended for private users. If you really want to have a look on Ebay for "Windows 10 Pro Key" and set the filter to low-priced

This is nonsense.

Both the same performance class.

Exactly, activate Windows 10 Pro on your laptop. It depends on the games you play. If there are, an RTX 2060 SUPER in a Bigtower housing is not enough for you.
