The Windows 2000 Readiness Analyzer tool analyzes your computer and reports potentially incompatible hardware devices and software programs. The tool compares the devices and programs on your computer against a list of known issues. Although this check also occurs during Windows 2000 Setup, you can download and run the tool before installing Windows 2000 to help ensure your installation will succeed.

NOTE: The list of potential issues reported by this tool is based on Microsoft and third-party testing, but is not exhaustive. For example, Microsoft did not focus on testing games or entertainment software. If you are concerned about any of your devices or programs, Microsoft strongly recommends you contact the hardware or software vendor directly to verify their compatibility status before purchasing Windows 2000. The Readiness Analyzer is only the first step in a successful upgrade process. When upgrading to Windows 2000, please take all the normal precautions for upgrading an operating system.
