You can use a tool called "winaero tweaker" and there enable an option called "take ownership" then when you right click the folder, you can take ownership of it and do whatever you want with it. Just be absolutely sure that it's not your main windows installation otherwise it'll be painful.
If you want to try something for free, you can check out genshin impact. Beautiful open and great music. Just don't get too deep into the gacha rabbit hole lol
What's there to transfer if they aren't to be found at all?
