Windows 10 RETAIL Key

Dear Concern and Reader,

First of all, I hope whoever is reading this finds you well and in the best of health.

Now, I have a question and hoping someone directly from Microsoft would reply or anybody who knows about RETAIL keys of Windows and software. I purchased Windows 10 Pro directly from **** Microsoft.COM - However, if I do not use my product key for a while until I get a new PC that would be appropriate to run Windows 10 Pro, does it gets deactivated on its own? According to some resources I found on Reddit and other social platforms. Or do I get to keep it forever and can use it anytime? Especially as I purchased my key from Microsoft and have the official receipt/invoice. I know if you purchase a retail key from another official/certified Microsoft stores, things can always go wrong or sometimes be OEM or fake products, but because I got mine from Microsoft, do I have to use it or can I not use it for a while?

I am asking this as my PC just recently broke down and I don't plan on purchasing a very expensive PC yet to run Windows 10 Pro. I currently have a new PC with Windows 11 Home and that's fine for me. Especially as a university Photography student, I own a MacBook and I am not at home ninety-nine per cent of the time (living on campus). So, if I don't use my product for a while or maybe a year or more go by, does it get deactivated or does it remain active, and can always be transferred to new hardware whenever I decide to use it again?

Lastly, I am sorry if I made any mistakes in my writing - I struggle with reading and writing due to learning difficulties, so I used Grammarly and I hope it is not bad at all.

Thanks,

Hammad
