Sometimes I get old computers donated to me that actually still run without reformatting and reconfiguring. It can be tedious to find drivers for old ISA sound cards and modems. Occasionally I simply clean all I can find from the OS and leave it as it came. The only problem is if you R click my computer and bring up properties it will say who it is registered to. Is there a way to delete the name ro change it without reformatting and reinstalling?

You say old computers, which OS are they running (Win9X, ME, XP)?

Alister

use regedit , but you will find the old users name all over the place

W98. And I'm not too sure how to use reg edit. Is there an easy way to get the drivers loaded to a floppy for the motherboard , sound card and modem? Then I could just reformat and do a clean install.

While it is a hassle to find the driver install files, you will probably spend less time doing a clean install, than searching for and removing every possible piece of personal info.
Also a clean install will most likely give the best chance of an effcient and troublefree system.
When I work on systems for donation, my first step is to install a NIC (if one is not already installed) and clone the drive to a temporary partition on another system. That way any drivers or files that exist are easily available..
next print out a full hardware list from SYSINFO.
I setup the system on a small rollaround table near my primary computer so while I'm working on something or surfing the net, I can turn around and do the mouse click/enter the info for the next step in the format/install/winupdate/reboot/reboot/reboot that it takes to do a complete install. While it takes a couple hours, I've only spent a few minutes of my time at points when it's convienent.
Downloading and saving on your HD or a cd-r all of the updates HERE
greatly speeds the update process.

download x-setup pro and you can change who the software is registered to.

I would not bother looking for drivers or re-installing anything if I were you
