Warning! new Win11 PC OneDrive problem

Just bought a new (Windows 11 Home) Microsoft Surface Pro 12. I needed to set it up as a new computer, not transferring from another machine (the old one was a very old Surface and the settings, etc. would not have been compatible). When I signed in to my Microsoft account to complete setup, Windows located our (cloud) OneDrive folders and set them up as the default Documents folder. This is not OK because we only use OneDrive to occasionally back up some files- all working files are stored on the local drive. I placed all my files in C/users/documents, but couldn't get Windows to recognize that as Documents folder. I tried to work around by renaming folders, but after restart everything was completely screwed up and not usable- so don't try that! I had to do a clean full reinstall, start over from scratch, and immediately removed the OneDrive app, went to Settings/ Accounts/ Windows Backup and make sure it was set to NOT backup to OneDrive. But still could not get Documents to reference the right location (the Properties/ Location tab was still not available). Ended up having to edit the registry key HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders. I replaced all OneDrive references with the desired folders. It worked. All this took hours of my life, after spending $1000 on a nice new computer. Not happy! But at least it's OK now.
