Windows 10: How many times can I reinstall windows before I have to buy a new product key?

I want to reinstall Windows 10. I've actually reinstalled windows on this machine a bunch of times, but I want to know if reinstalling windows affects activation in any way, like, will I have to purchase a new product key and stuff after a particular number of reinstalls? I'm on Windows 11 Home Single Language btw

How to retain the lost product key?

There is nothing you can do. The software itself is nothing. All of the money is in the product key. Throw that away and the only recourse is to buy Windows again in order to get a new key.

At least if he buys Windows from the Windows Store his product key is preserved in his Store account permanently and he can retrieve it just by logging in. I suggest that his next step is to purchase Windows from the Windows Store. He won't have to reinstall
Windows if he buys the same edition as is on the hard drive now.

 

Reinstall Windows 10 with OEM product key

When you upgraded from a previous version of Windows or receive a new computer preinstalled with Windows 10, what happened is the hardware (your PC) will get a digital entitlement, where a unique signature of the computer will be stored on Microsoft
Activation Servers. The Windows 7 or Windows 8 genuine license you were previously running will be exchanged for a diagnostics key.

Anytime you need to reinstall Windows 10 on that machine, just proceed to reinstall Windows 10. It will automatically reactivate.
You will prompted to enter a product key a couple times through the installation, click I don't have a key and Do this later.

There is no need to know or get a new key, but if you have issues with Digital Licensing or the Activation Troubleshooter, you can utilize an existing Windows 7 or Windows 8/8.1 product key
you already ownto reactivate if necessary. or use the reset function in Windows 10.
