In folder options, is "open each folder in the same window" checked. If not, perhaps that would help. Worth a try.
Another thing you could try would be to run the system file checker. Open administrative command window and type sfc /scannow, and hit enter, and wait a few minutes for it to complete. It will check your system files for corruption and fix if possible if any is found.
Otherwise, perhaps a "repair install
" which does not wipe out your programs, settings, and data, might be worth trying.
Another possible fix would be to create a new user account and see if the objectionable behavior happens when you're in that account. If not, from within the new account, you could copy over all your folders and files that are under your old User/user name into the appropriate place in your newly created account and hope that the problem doesn't transfer to the new account along with old your folders and files.
If that last approach fixes the problem, then after you're very sure everything is working properly with all your transferred folders, apps, files, etc., you could delete the old user account.
