So Windows would work like a charm again once logged into another
account if the problem is software? Also would doing a clean install
touch personal data on Windows? I am not sure and have given out
technical advice to others using the mac defs. On a Mac a clean install
would just create a new system folder but would not touch personal
documents.

Windows XP has a "Repair Install" capability, if you have the retail
installer CD handy. A Repair Install leaves user data and applications
installations intact. It won't remove malware. You need to reinstall
Service Packs, security updated (from Windows Update). There are also
complications with respect to Internet Explorer (i.e. Microsoft
recommends removing IE8, before the Repair Install - most people
won't be doing a Repair Install for fun, so I don't see how this
is a very convenient way of having set up versions of IE past
IE6.) There may be a similar issue to research, with Windows
Media Player.

WinXP also has "System Restore", which preserves some of the changes
made to each partition. There are rules about what is tracked
and what is not. For some trivial issues (like small problems
with my graphics card), I can "go backwards in time" to a time
when the system was working well. That could be something as
simple as backing out some change to the registry. If you've
turned off System Restore, then there won't be any tracking
of changes.

If you use System Restore while in a normal session, you can also
undo it. So if today is Friday, you can go back to Tuesday, and
then go forward to Friday again.
But System Restore isn't a cure for malware either, because
the first thing malware attacks, is System Restore. All the
Restore Points will be infected.

There is a tool called System File Checker, which has the capability
to put back copies of system files. You may be asked to insert
the install CD, for it to work. When I tried it for fun,
I needed to make two registry changes with Regedit, before
it would run.
And as far as I'm concerned, it's hardly ever likely to
"save your bacon". Too many nasty things can happen to
your install, for something as simple as that to fix it.
But since I'm listing various tools, it deserves honorable
runner-up mention.

Creating another user account, might be a cure for a
"corrupted profile", whatever that is.

In addition to all of those, your Dell/HP/Gateway/Acer may have
its own version of file restoration tools. Those can range
from "nuke and rebuild", often with no warning of the consequences,
to more intelligent methods, that are closer to a Repair Install.
Not only should you read the Laptop User Manual, but you should
also google to see how much damage or difficulty, any method
like that is known to cause. I think my new laptop has at least
one "nuke and rebuild" type option. I have a full backup of
that machine, to protect me.
