PaulSc,
Look at my FAQ:
faq608-0 Win98, to backup the registry, go to Start>Run, and type scanregw. Choose Yes to backup the registry again.
In Win95, open regedit, select the key(s) you are making the change to, choose Registry>Export Registry File from the menu. Save the file to your desktop. If you have problems, double-click on that saved .reg file to undo the change you made. If everything works OK, delete the .reg file from the dsktop.
