Will reinstalling patches on top of another cause any issue?

Having discovered Qchain, I was wondering if I can re-install a hotfix on top on a version already installed. The reason I ask is some of the pc's have been patched with various patches (all xp machines, don't ask me why but this was the set up when I get here)
I have created a folder containing the hotfixes, a copy of qchain and a batch file.
If I was to run the batch file and the hotfix included in the batch file was already installed would that cause any complications.
Thanks

Reinstalling hotfixes is not a problem.  It is indeed necessary in some instances....

"Hotfixes are applied only to software that is already installed when you apply the hotfixes. For example, if you remove a component and later reinstall it, you must reinstall any hotfixes that apply for that component. In addition, if you add further components to your computer that require this hotfix, you must install the hotfix again. Fixes included in a service pack do not work the same way. After you install a service pack, fixes are applied to all components you add or reinstall without you having to reinstall the service pack." - MS hotfix deplyment guide.

Sorry what I meant was O/S patches & critical updates  such as KB824146,  KB824141 etc.

I would try it on a test machine.  An updated version of Qchain is avaliabe that fixes some problems.  http://support.microsoft.com/default.aspx?kbid=815062

The patch is not being throughly tested, I would put them on a test machine (server) before install onto a mission critical system like the exchange or oracle database machine

service pack on the other hand is more throughly tested by Microsoft, there is less issue with it, but still test machine is the keep, what you may want to be more specific about is :

what OS do you have?
what serivice pack level you have?
what critical application you have running on that machine
can you accept system not booting up ?
do you have a complete backup ? (you should always, in case...)
you may want to use a ghosted machine to test

good software to try is the Shvlik NetChekPro, it has in depth study of the patches issued by microsoft,
