Customizer 2000 is a special utility which is designed to optimize Windows 95/98/ME performance. The program lets you explore the many hidden settings in Windows, and make changes. Modifying a setting simply involves reading a helpful description, and clicking a checkbox. Customizer 2000 allows you to change boot-up options, as well as your registered name and organization, and the location of the Windows directory.

You can also have unknown file types automatically opened with Notepad; enable a CD-ROM cache; customize the Start Menu; and remove the arrows from your desktop shortcuts. In addition, the program includes an Internet optimization function which can improve your modem throughput.
