By default, System Restore monitors all partitions. So, for example, if you delete an executable file, you can have the system state revert to a specific restore point to recreate or repair the executable file. When you revert to a restore point, however, you lose all changes since that point, except for changes to files in the My Documents folder and documents you've created with applications such as Microsoft Word and Microsoft Excel.
If you use System Restore and don't like the new system state, you can undo the process and restore the machine to the system state it had before you ran System Restore. Alternatively, you can run System Restore to change the system state to a different restore point.
