I just got a hold of nLite, because I would like to create my own DVD with the default Windows XP Home Edition-installation,
but with all updates that come with Windows Update.
Is this possible..? If so, which tab should I use to add them..? Is it "Hotfixes, Addons and Update Packs"..?
Where would I find them then..? In the "C:\WINDOWS" folder..?

I don't want to remove anything from the original installation or add any other programs.

If I got Service Pack 2 through Windows Update, do I still need to use the "Service Pack"-tab to add it..?

Another thing....
What's special about the Add-ons at the nLite site and the "Add-on"-section in this forum..?
Don't other programs work?

1) if your Xp cd comes as "SP1", you'll need SP2.exe to include it in your DVD
2) if you want "post SP2" updates to be included too, you need an update pack like RyanVM's
3) if you want other programs to be included, you can use those addons you found on this site. You don't just add the program on the disk, the addon makes the program included in XP when installatiuon is finished.
4) you include SP2 in "Service Pack", post SP2 updates and addons in the "Hotfixes, addons" part of nLite.
If the programs you want to include are not to be found as addons yet, you can make your own, there are explanations about how to in the ddon forum.
I hope I answered all your questions. If not, someone else will finish.

Ponch, thank you for the answer, but you didn't answer the one question that I really wanted an answer to.
The only thing that I really want is to have all Windows-updates integrated into the files on the CD.
Here's how I thought it would work:

I update Windows through Windows Update and then use nLite to incorporate all the updates into the files from the CD.
If that's not possible, is there any other way to get all updates and put them on a DVD..?

You can get them in the RVM Update pack (recommended) or extract them from the Autopatcher (not tested by me but some do that).

Do a search you'll find them easily.

I think I did
That's what we all want and do.
That's where you are wrong, nLite and Ryan's pack are way easier
That's where you need to read my answer.

Thank you both for the help. I think I can handle it on my own from here on.
One thing though....
Can I just download all updates from Microsoft's Download Center and use those files instead...?
It will take some time to download them all, but maybe there are compatibilityissues between the languages.
I don't have an English version of Windows XP, so I figure it's more safe to use the updates that are meant for my version.
They come, or some of them do, in .exe-files, and I have read that I should extract the files from within them.
Is that all..? There's nothing else to it..? It wasn't so hard after all.

Yes you can download them and use the exe files, don't tamper with them in any way.

The first file in the list of the updates that I have got from Windows Update is "Update for Background Intelligent Transfer Service (BITS) 2.0 and WinHTTP 5.1".
Should I download the file, which has the name "WindowsXP-KB842773-v2-x86-sve.exe", and add it with the "Hotfixes, Addons and Update Packs"-tab..?
Do I add the rest of the files after each other after that, with the exception of Service Pack 2, of course, which I add with the "Service Pack"-tab..?

If nothing else works, I'll try RyanVM's files.

Why wait? It is only 44mb and saves your time by manually adding stuff. Just make sure to integrate that pack last.

I'll go with the RyanVM-files, because the files at Microsoft's Download Center are not named properly,
so I might run into problems, so then I might as well use the prepackaged files from RyanVM.
Anyhow, what's the difference between RyanVM's Windows XP Post-SP2 Update Pack and RyanVM Integrator..?
My guess is that the Update Pack contains all the files, and the Integrator sounds like a utility, but what can it do..?

Edit: The Integrator sounds lilke a complementary or replacement for nLite.

Unfortunately, RyanVM's pack is intended for english versions only and there is no swedish translation yet.

I was saved by someone else who told me that he has Swedish files.
I'll try those and see if everything works as it should.

I'm sorry for bumping, but I asked about this at another forum as well,
and someone said that he had heard about a utility that searches for updates for you,
and then it gives you a list of updates that you can download.
He said that I should look around for it at the nLite-forums.
Is there such a thing..?

Edit: When integrating all the hotfixes in the "Hotfixes, Addons and Update Packs"-tab in nLite, I was told to sort everything by date,
with 2004 at the top and 2007 at the bottom.
I want to Integrate Internet Explorer 7, and it doesn't have a date, so where should it be..?
Should it be at the top or at the bottom?
There is another file with the name KB888111 or the like, and it doesn't have a date either.
Is sorting crucial to the operation, or can I leave everything be..?

Edit 2: I went through the process of integrating everything, and then created an .iso-file, but I find the size confusing.
The files on the original CD take up about 552 MB.
After integrating Service Pack 2 and all updates thereafter, the folder with Windows-files is 610 MB large.
That's not much to me, because Service Pack 2 alone is about 271 MB, and the rest of the updates take up close to 178 MB.
Together, they take up 449 MB.
Then, I added Windows Media Player 11 which added a couple of megabytes so that the folder is 626 MB in total.
After generating an .iso-file, the file is 617 MB large.

First, should it be that small..? Sure, much of what I included could be overwriting previous files, but 449 MB..?
Shouldn't it be a bit bigger than 617 MB..?

Second, is this the best way to go..?
First I integrated Service Pack 2 and the post-Service Pack 2-updates with nLite.
Then I integrated Windows Media Player 11 with Windows Media Player 11 Slipstreamer.
Finally, I used nLite to create an .iso-file.

Edit 3: I was pointed in the right direction to find the utility that I mentioned,
and you can find it here.
