The Windows 2000 Hardware Compatibility List (HCL) is a compilation of systems and hardware that has been extensively tested with Windows 2000 for stability and compatibility. It is the guide used by Microsoft Product Support Services for determining whether a given system is supported for use with Windows 2000.

If you experience problems during your installation of Windows 2000, your first troubleshooting step is to verify all of your computer's hardware components against this list.
To see the version of the HCL that was released with Windows 2000, on the Windows 2000 CD-ROM, in the Support folder, open Hcl.txt.

Updated versions of the HCL are available on:

• The World Wide Web at: http://www.microsoft.com/whdc/hcl/search.mspx
• The Microsoft FTP server at ftp://ftp.microsoft.com/bussys/winnt/winnt-docs/hcl/
