Your computer must have a minimum speed of 300 mHz and a Pentium II, Pentium III, Pentium IV, Celeron, Athlon, Duron or Via-Cyrex processor with at least 64 meg of RAM and a 3 gigabyte or larger hard drive with at least 1 gigabyte free in order to upgrade to Windows 2000.

Computers that cannot be upgraded include: Compaq 4540, Packard Bell D141, and any other computer that is over 5 years old.

Before installing, insure that you have an adequate number of free Windows 2000 Professional licenses to cover the upgrade of your machine. If you have a site license or multiple computer license, use one of the license numbers indicated on the license. If there is more than one number, try to choose one not currently in use and note on the license to which computer that number will be assigned.

Reinstallation: Computers purchased with Windows 2000 Professional have a Microsoft sticker on the side or front of the system box containing a printed security code for that machine.

Upgrade procedure:

• Before upgrade
  • Save essential files on floppy or other backup location
  • Clean off any unneeded stuff to gain at least 1 gigabyte of space on the hard drive.
  • Empty the Recycle Bin.
  • Defragment your hard drive
• Install the Windows 2000 Pro CD
  • When it asks if you want to upgrade, say yes.
  • Enter the security code when prompted.
  • It is generally better to enter yes when asked if you want to use NTFS file system. This makes the hard drive more secure and error free. Enter no only if there are known compatibility issues.
• Updates & Service Packs
  • Apply Service Pack 2 or newer
  • Uncheck the Automatic update features if advised to do so by your IT staff.
