http://www.microsoft.com/windowsxp/home/upgrading/advisor.mspxIf you start the Windows XP Setup program to start the upgrade while you are running another operating system, Windows XP automatically runs the Windows XP Upgrade Advisor. However, in this case the Windows XP Upgrade Advisor generates a limited report that only describes the blocking issues, not the whole report. If you want to create the full report (that is saved as the Upgrade.txt file) without upgrading, run the winnt32 /checkupgradeonly command from the I386 folder on the Windows XP CD-ROM.
Note If you select Dynamic Update when you run the winnt32 /checkupgradeonly command, the appropriate drivers and fixes are downloaded. Therefore, when you run the upgrade and select Dynamic Update (recommended), you do not have to download the drivers again.

You may want to determine if there are any updates or service packs that are available for the software before you start the upgrade. If you have these updates available during the upgrade, the software may work correctly with Windows XP. Additionally, if you are not sure about the compatibility of particular software, we recommend that you remove the software before you upgrade the operating system because you may not be able to correctly remove it after you upgrade to Windows XP.
