Windows 2000 SP2 Encryption
Windows 2000 SP2 automatically upgrades your system to 128-bit encryption. It is not possible to disable or uninstall this feature. If you remove Windows 2000 SP2 after installation, your system continues to use 128-bit encryption; it does not revert to back to 56-bit encryption. Windows 2000 SP2 adds high encryption support for all Windows 2000 encryption-based services, including Kerberos, Encrypting File System, RAS, RPC, SSL/TLS, CryptoAPI, Terminal Services RDP, and IPSec. High encryption support improves the security of local data and online transactions, as well as any other content you share over networks or the Internet.

For more information on 128-bit encryption, read the High Encryption Market Bulletin. (This site is in English.)

Note Uninstalling Windows 2000 SP2 does not revert your computer to the standard encryption level. You can always uninstall Windows 2000 SP2, but your computer retains high encryption support.

For a list of the updates included in Windows 2000 SP2, read Microsoft Knowledge Base (KB) Article Q282522. (This site is in English.) System Requirements

- Operating System: Windows 2000 Professional, Windows 2000 Server, Windows 2000 Advanced Server, or Windows 2000 with Server Appliance Kit.
