Get The Drivers You Need

Visit Windows Update (XP Only)
Look at the left hand pane and under Other Options click Personalize Windows Update.
Now in the right hand pane check the box - Display the link to the Windows Update Catalog under See Also
Below Choose which categories and updates to display on Windows Update - make sure you check all the boxes you want shown.
Click Save Settings
Now look in the left hand pane under See Also click Windows Update Catalog and choose what you're looking for. Choose either MS updates or drivers for hardware devices.
Start the Wizard and off you go.

There are a TON of drivers there. I highly recommend you take a look at this page prior to downloading something from the web.

Save Your New Downloads

Since some people are still using modems and since MS is issuing es right and left for XP wouldn't it be nice if after you downloaded all the updates you could save them? Well, you can and MS has provided a way for you to do it.
Here's How:
1. Logon to Windows Update
2. Choose Windows Update Catalogue (left hand pane)
3. Choose Find updates for Microsoft Windows operating systems (right hand pane)
4. Choose your version and language then Search
5. Choose one the following:
6. Critical Updates and Service Packs
7. Service Packs and Recommended Downloads
8. Multi-Language Features (0)
9. Once chosen simply click on what you want to download and then back at the top click Review Download Basket
10. You are taken to the next page where at the top you can specify where the downloads are to be saved.
11. Click Download now.

Each will make a directory under the root of the folder you saved them to. Once finished you need to go to where you saved the file (s) to and then simply install all your es.
Read-me's are available in each section so you know which one you are installing.
