When you find one, double click it and select "open in explorer." You are now ready to create your batch file. Navigate to C:/Windows and open the folder where Windows is installed. Inside the Windows folder, open a new batch file and add any commands or text you would like. Save as whatever extension you prefer.
Open Windows Explorer and double-click the newly created batch file. Navigate to the directory where you want your file saved and double click on the existing file that you want copied. Click "copy" and wait for your file to be copied into the directory you specified. That's all there is to Batch file maker! Start > Run and type "safe restore". A window will appear, just click on "OK". Once you are done restoring your computer back to an earlier time, simply make sure you create a backup of all your changes before you make any further changes to your batch file.
