Troubleshooting

There aren't many potential problems with using categories. The only danger exists if you're modifying the Registry to share the Master Category List with other users. Any time you modify the Registry, there's the potential to corrupt the Registry, accidentally remove a key, or enter a key in the wrong format or in the wrong place.

You should always back up the Registry before you begin any modifications. Detailed instructions for backing up and restoring the registry can be found in Appendix E, "Working with the Windows Registry." There are also programs on the market today that will enable you to restore your entire computer to a safe point, should something go wrong. Those are valuable options, but be certain that you understand the risks and benefits of using one of those programs.
