Disk Defragmentation 
A defragmentation utility is included with Windows 2000. Several vendors sell 
this utility as well such as DiskKeeper. Make certain you defragment your disk 
drives on a periodic basis. You must close all programs before beginning. The 
process can take a long time.  We will not do this here. 
Creating an Emergency Repair Disk 
You should create an emergency repair disk as soon as possible. Use this disk if 
your system files are damaged or your computer won't start. The disk includes 
system settings such as registry files, disk partitions, and installed devices. Make 
a new repair disk every time you make changes to your hardware or software. 
Emergency Repair Disks are specific for each computer.
