Hi there. My question(s) here was for what supported operating systems meant - to the regards of what's mandatory or not for dell computers that runs on windows?

I happen to have a dell laptop from 2015 and have a recovery tool for it that's a windows 10 32 bit system. It says here on the dell website that my laptop supports both windows 8.1 64 bit to 10 64 bit.

Could a windows 8.1 32 bit and windows 10 32 bit work for my laptop as well? Or does "supported operating systems" mean only that specific operating system can only go on there?
