Visual Studio automatically saves your settings every time you close it. To see where this file is located (or to change the location) go to Tools -> Options -> Import and Export Settings:
The nice thing is you can use this to "undo" any changes you have made during a session. So if you made a bunch of changes to Visual Studio but don't want to keep them then you can import the CurrentSettings.vssettings (default name) file to bring back your settings from the last time it was closed.
