I saw that it can be done and found other pages explaining how. Here is an example: https://answers.microsoft.com/en-us/windows/forum/all/how-to-reset-windows-size-and-position/fc76442b-1083-4a40-b8a3-6766bf3083cd.

The problem is that figuring out how to do it for each software, and then always doing it for each one, is a headache.

Is there a way to do it faster?

Is it possible that Windows doesn't save such data in a single folder, or something like that, so that one can simply delete everything to reset everything at once?
