Although Windows has many build-in device drivers, I prefer to install or update the device drivers with the most recent drivers from the manufacturer.
I have frequently seen, things going wrong (blue screen) after updating device drivers from the Windows update website.
Besides installing the Windows updates, you can choose to update all Microsoft products like MS-Office.
Therefore, you go to the Windows Update page and choose for Microsoft-Updates in the menu bar. If you have just reinstalled Windows XP, it's wise to update directly with the latest available Service Pack.
After you installed the high priority critical updates, restart Windows and visit the Windows Update website again.
This will delete the update installation files and the update history and restore the update function.That's why you better install one device driver update at a time.If the new driver is giving a BSOD (Bleu Screen Of Death), boot in safe mode (press F8 at reboot), Control Panel, System, tab Hardware, button Device Manager, right click the updated hardware, select Properties, tab Driver, button Roll Back Driver.You can download (and install) the Service Pack files directly from the Windows Update site or download the Service Pack file first from the Microsoft download centre (You can directly install the latest service pack, there is no need to install the previous service pack's!
