Windows 2000 Service Packs
Service packs are cumulative updates that include security patches, bug fixes, and driver updates. Microsoft released four service packs for Windows 2000.
| Service Pack | Release Date | Key Changes |
|---|---|---|
| SP1 | July 2000 | USB device fixes, security updates, Y2K fixes |
| SP2 | May 2001 | 128-bit encryption enabled by default, IE 5.01 SP2 included |
| SP3 | August 2002 | All post-SP2 hotfixes, USB 2.0 support, IPSec improvements |
| SP4 | June 2003 | All post-SP3 hotfixes, USB 2.0 refinements, COM+ reliability |
Installing Service Pack 4
- Download
W2KSP4_EN.EXE(135 MB) from the Microsoft Download Center. - Close all running applications and disable antivirus software temporarily.
- Run the executable and follow the wizard. Select Create Uninstall Folder to allow rollback.
- Restart the server when prompted.
- After reboot, verify the version: right-click My Computer → Properties. The General tab should show "Service Pack 4".
Slipstreaming
To create an installation CD that includes the service pack, use the /integrate switch:
W2KSP4_EN.EXE /integrate:D:\Win2000CD
This integrates SP4 into the installation files at the specified path, so new installations are fully patched from the start.
Post-SP4 Updates
After SP4, Microsoft released the Update Rollup 1 for SP4 (September 2005), which bundles all critical hotfixes published after SP4. It is the final update set for Windows 2000.
