Windows 10: Is there a way to see if I can use a previously purchased Windows key?

I have a kind of unique situation and hoping to see if I can use an previously purchased version of Windows 11 from Newegg.com. I have the key in my email, but I thought that I had used it to upgrade a different PC. Looking at my PCs, none of the Windows keys match the purchased key. I've been building a new PC and was hoping to use the key from Newegg for this PC. Is there a way to see if a Windows key is in use, or do I just need to try to use the key and see if it works? Thank you in advance!

installing previously purchased (and installed) game on new hard drive

I bought it from the Microsoft store. I can see it in my previously purchased list but It's not allowing me to install the game. Was wondering if it only limited it to one install per purchase or something?
