Make a folder on your hard drive and copy these files from the windows directory. Also copy win.ini and system.ini to this folder. If you are showing all files in windows explorer this is an easy task, you can just right click to copy and then right click on the destination folder and paste. All you'll have to do is double click the batch file from anywhere in Windows when you want to create or update your backups. A batch file is basically a text based file that contains DOS commands that are executed in sequence when you run the batch file.
Batch files can be very powerful and can use simple programming commands as well.
I recommend that you never run a batch file unless you view it and understand the commands that it is going to execute. While I would never do anything to harm you, some cretinous wretch could wipe you out with a single command in a batch file. For that reason I am going to go through the batch file with you step by step and explain the commands. If you are running Windows 98 and are not interested in the batch files, scroll down because I will also be providing information on how to effectively use the Windows 98 Registry Checker and the Scanreg utility to backup and restore configuration files. Note the switches I am using with the copy command.
