the whole point is the hardware that is supported by XP directly is now five to ten years old.
No manufacturer is going to write updated drivers for ten year old hardware.
It just doesn't happen. two years is about the max... XP came out in 2003 or so?
example
Included driver... Soundblaster
last update by Creative labs was in 2000...
and there will not be another update for the Creative labs soundblaster card... Never Ever.
It is a very popular card. It will be found in LOTS and LOTS of old computers.
We are not going to add it to the sound packs... Never Ever....
BECAUSE IT IS included with windows. There is no update for it now... and there never will be!!!
True it is a VERY OLD driver... but there is no newer one than the one provided by MS...
Even if there was, Who Cares?
If you decide against taking our advise and delete the soundblaster driver from windows with nLite-
then you give up ANY and all driver support for the soundblaster card...
(sure you saved 10 kbytes, so what? It's not enough to matter...
you could save a lot more space deleting the Help files, and nowone will ever need those 
another example
standard IDE driver... no updates never will be... If you delete the OS's included IDE driver then you have no IDE support.
NO... We are not going to add a standard IDE driver to the packs
BECAUSE IT IS included with windows. There is no update for it now... and there never will be!!!
True it is a VERY OLD driver (perhaps 1995)... but there is no newer one than the one provided by MS...
Even if there was, Who Cares?
Who said anything about screws? - I said "HANG" it...
- pull the IDE and power cable off their CD ROM
- plug the IDE cable and power into your DVD. Set the DVD ROM on a small box or pile of books NEXT TO, OR ON the open cabinet.
- you don't have to actually INSTALL IT just "hang" it there for 30 min until the install is done
using the existing CD ROM's cables.
Even if you include the time to open the cabinet... we are talking about ten seconds worth of work 
Lets face it, If you are servicing the unit then you have to take the side off and check the CPU fan anyway, so really it's like two seconds work.
If someone does not have 20 bucks for a DVD they cant afford to have me fix their PC any way 
I keep a couple extra in my car and in my truck and i have several in my office. I buy them five and ten at a time 
In the old days I did the same for floppy drives 
for 15 bucks you can get a USB to IDE cable (I always have one of those with me too)
If you think you can't get prices like these, then I infer you have never been to NewEgg.com or tigerdirect
