We had used VMWare to have multiple Operating Systems on the same
machine. I am not sure whether you can clean your OS using VMWare.
Here are my views on VMWare Workstation,
Suggestion out of experience:
1. Host OS should be running on 128MB and, if you are running multiple
Guest OS's simultaneously, each guest should have 96MB. Otherwise it is
dead slow. We had 384MB, with one host and three Guest OS's installed
and was running the host with two Guest's simultaneously.
2. While partitioning, it is advisable to have at least 4GB space where
VMware is installed, because while installing multiple
browsers(Netscape) on the Guest OS's a lot of space is required. The
other reason is there is no option to increase the partition after the
installation of VMware or the Guest OS's.
3. For MS IE4.0, you should have separate OS's, since once you install
Internet Explorer 5.0 you will not be able to revert to previous
4. You will not be able to view the files (Downloaded or even those
present by default) under any Guest OS, they are present virtually, so
if you want to access them you have to save it to a common machine in
the network, where it can be accessed later for testing or other
5. It is advisable to have backup copies of VMware Guest OS's files
(*.dsk), because when you have problems with VMware, which are not
rectifiable, and there is a situation wherein you have redo the whole
system, you can copy those *.dsk files to appropriate directory and save
6. The step by step installation procedure for installing VMware can be
found at http://www.vmware.com/pdf/gettingstarted_2_win.pdf

Have you tried using the Ghost approach? You build a clean environment from
scratch & then save the image of that on a server and then restore it
anytime you want. We use it all the time (we have a library of images with
different OS's, browsers and so forth) to allow us to minimize setup time
for each round of testing and also to ensure a clean uncontaminated machine.
I would definitely look at the VMWare solution since I have never found
a good way of 'getting back to' a clean OS environment. There are just
to many things going on in the Windows OS to ever really know what has
changed. When I actually care about the changes I use PC Magazines
InCntrl system monitor program.
The way that I have handled getting back to a known state in the past is
by backing up or ghosting the machine after setting up the baseline
configuration. Then doing a restore to go back to the base state. This
will work but the VMWare solution is faster.

Quality is the result of a carefully constructed cultural environment. It has to be the fabric of the organization, not part of the fabric.
