If you have totally messed up your user settings in SSMS. You’ll find it’s not as easy as deleting your user settings file:
C:\Users\<user>\AppData\Roaming\Microsoft\SQL Server Management Studio
After deleting SSMS will restore the previous settings from somewhere in the application. The best way to reset them totally is to run reset setting from a command prompt. First find ssms.exe mine was in:
C:\Program Files (x86)\Microsoft SQL Server Management Studio 18\Common7\IDE
Then run:
.\ssms.exe /resetsettings
That’s it SSMS will boot up with a fresh user settings file.
