Reformat in Windows 2000 without Updates

You will not be able to safely update unless you can obtain a hardware firewall or a CD/DVD of the updates.

If you own a laptop computer, you can bring it into the CUIT Computing Support Center at 202 Philosophy Hall for assistance.

If you own a desktop computer, you will need to contact CUIT at x4-1919 in order to make other arrangements.

Once you have managed to install the updates in a secure fashion, the remaining steps are:

Print out this page, if possible.
Contact CUIT to have your network access restored.
Now, you may reconnect to the network safely.
Go to http://windowsupdate.microsoft.com and install all remaining critical updates. You may have to reboot your machine multiple times and go back to the Windows Update page before the process is complete. As soon as it tells you that there are no remaining critical updates to install, you are finished.
Set Windows Update to download future updates automatically.
Install Norton Anti-Virus from the CUIT Security Downloads page.
Reinstall programs and all files you backed up.
