RDilly makes a backup copy of the Windows registry. It is very similar to System Restore found in WinME and WinXP. You get a point-in-time copy of the registry labeled with the date it was made, which you are able to restore at a later time. Note that you need Administrator or Backup Operator rights to run this program.
Download the ZIP package and extract to a folder of your choice. Launch the application by double-clicking on RDilly.exe (which will make a point-in-time copy of the registry immediately) or schedule to run it periodically. To restore to one of the copies, double-click on RDillyRestore.bat, or launch using RDilly.exe -MainForm.
