Where can I get Service Pack 1 for Windows 2000 and what's new?

Copies the Service Pack files locally (if you just want to expand and not install you can use the /x switch as with other service packs)

Backs up the current file set and registry information on the local computer

Based on the system catalog, modifies Windows File Protection service (WFP) to reflect the new Service Pack files

Updates the encryption files according to the encryption level of the currently installed operating system (56 or 128, there are not separate versions of the service pack)

Updates the necessary system files

Updates the registry with any new or modified registry keys

Installs a new driver.cab file that Setup and other components can use to install device drivers without requiring access to the network or the Service Pack CD

Updates Drvindex.inf with the new drivers contained in the Service Pack driver .cab file

Updates Layout.inf, which identifies which files to install from the operating system media and which files to install from the Service Pack media

Writes a ServicePackSourcePath registry key, which Setup uses to identify the location of the Service Pack media when it needs future files

Creates the $NTServicePackUninstall$ folder to store the uninstall information and compresses if NTFS

Creates a log file that identifies the command line used to initiate the Update.exe program and the files copied to the computer by the Update.exe program

Makes an entry in the event log about the installation
