Hi @zequion,
Welcome to Microsoft Q&A!
Which version of Visual Studio are you using? Do you mean the position of document windows are changed when reopening the project?
Please go to Tools > Options > Projects and Solutions > General > ensure that the option “Reopen documents on solution load” is checked.
If it has been enabled, please reset your VS settings and try again.
Besides, you can also customize a window layout to arrange window positions and behavior, which will make VS remember it. Please see Customize window layouts and personalize tabs.
Sincerely,
Anna
