Hi Laura, Thanks for posting here in Microsoft community, to find out what version of Windows you have, on your computer device simply press Windows key + R on your keyboard then Type winver and hit Enter button.
A window will pop up showing your Windows version and build number.
It’ll say something like “Windows 10 Version 22H2” or “Windows 11 Version 23H2
I hope this helps you out, let me know how it goes.
