1.4 Service Pack 1 Encryption

Installing this Service Pack does not change your current encryption level. Setup determines the encryption level—either standard (56-bit) or high (128-bit) encryption—of your operating system and automatically installs the Service Pack with the same encryption level.

If you wish to update your encryption level (from 56-bit to 128-bit) after Service Pack 1 is installed, run the High Encryption Pack from the Microsoft Windows 2000 Web site. There is no need to reinstall Service Pack 1 after you run the High Encryption Pack.
