Verify program compatibilityFor information about program compatibility and about migrating from Windows Millennium Edition or Windows 98, visit the following Microsoft Web site:
Verify hardware compatibilityFor information about compatible hardware for Windows XP, view the Windows Hardware Compatibility List (HCL). This list is a compilation of computers and computer hardware that have been extensively tested with Windows for stability and compatibility. Microsoft Product Support Services (PSS) uses the HCL to determine if a computer is supported for use with Windows. To view the latest HCL, visit the following Microsoft Web site:
Run the Windows XP Upgrade AdvisorYou can use the Microsoft Windows XP Upgrade Advisor tool to audit the current status of your computer and to receive a report of known hardware and software compatibility issues (based on Microsoft testing before release). If you are concerned about the results of the report, do not upgrade until these concerns are resolved. Contact your hardware or software manufacturer for updates that make the products run correctly on Windows XP.
If you are considering an upgrade to Windows XP Home Edition or to Windows XP Professional, and you do not have a Windows XP CD-ROM, you can download the Windows XP Upgrade Advisor. To do this, visit the following Microsoft Web site, and then click Download the Upgrade Advisor: 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.
To run the winnt32 /checkupgradeonly command:
- Click Start, click Run, type cmd in the Open box, and then press ENTER.
- Type CD-ROM drive letter:, and then press ENTER.
CD-ROM drive letter is the drive letter of the CD-ROM or DVD-ROM drive where the Windows XP CD-ROM is inserted.
- Type cd i386, and then press ENTER.
- Type winnt32 /checkupgradeonly, and then press ENTER.

Note If your computer has one or more compressed drives or one or more programs or services are running, the Windows XP Upgrade Advisor or a Windows XP upgrade may not work.
The Dynamic Update featureWindows XP Setup includes the Dynamic Update feature. Dynamic Update downloads and uses critical content to enhance the Windows XP Setup program. If the computer can connect to the Internet while the Windows XP Setup program is running, Dynamic Update prompts you to download critical content. You can skip Dynamic Update, but we strongly recommend that you do not skip it.
For additional information about Dynamic Update, click the following article numbers to view the articles in the Microsoft Knowledge Base:
Quit any programs that are runningTo remove potential problems with services and programs that are running, use of one of the following options:
- Quit any programs that are running. To see a list of all running programs, press CTRL+ALT+DELETE to view the Close Program dialog box. When you limit the number of running programs, additional resources are available for the Windows XP Setup program, and you help prevent issues between the Setup program and the running programs.

192926 How to perform clean-boot troubleshooting for Windows 98
- Click Start, click Run, type msconfig, and then click OK.
- Click Selective Startup.
- Clear all the check boxes, and then click OK.
- Restart the computer, and then try to run the Windows XP Setup program or Windows XP Upgrade Advisor again.
- Start your computer in safe mode, and then run the winnt32.exe command to run the upgrade, or run the winnt32.exe /checkupgradeonly to run the Upgrade Advisor. Safe mode uses only a minimal set of drivers, services, and programs. Safe mode can help simplify the installation and remove items that may interfere with the upgrade. However, safe mode does not affect the upgrade. Items that are not loaded are still examined and may be included in the report.
For additional information about how to access your CD-ROM drive in safe mode, click the following article number to view the article in the Microsoft Knowledge Base:
Back up your computerWarning Windows XP has a removal option. However, you cannot remove Windows XP after the upgrade if you upgraded from Windows 2000 Professional, or if the file system was changed to the NTFS file system.
Back up your computer contents, including all your data, before you start the upgrade. With this backup, you can easily restore your data files if you decide to reinstall your previous operating system.
For additional information about how to make a backup of your Windows 98-based or Windows Millennium Edition-based computer, click the following article numbers to view the articles in the Microsoft Knowledge Base:
Upgrade the computer BIOSBefore you start the upgrade, obtain and install the latest basic input output system (BIOS) upgrade for your computer from the computer manufacturer. If you update the BIOS after you upgrade the computer, you may have to reinstall Windows XP to take advantage of features such as Advanced Configuration and Power Interface (ACPI) support in the BIOS. Update the firmware in all devices before you start the upgrade if you can.
Warning If you upgrade or flash the BIOS with an incorrect version for your specific motherboard, you can severely damage the motherboard. Therefore, do not work with the BIOS of your computer unless you are very familiar with how to do this, or you have obtained thorough instructions about how to safely do so.
For information about hardware and BIOS updates, visit the following third-party Web site:
Turn off power managementMake sure that power management is turned off in Windows 98 or Windows Millennium Edition in the Power tool in Control Panel. To turn off Power Management:
- Click Start, point to Settings, click Control Panel, and then double-click Power Management.
- Click the Power Scheme tab.
- Set Turn off monitor to Never.
- Set Turn off hard disks to Never.
- Set System standby to Never.
Remove or disable antivirus softwareRemove or disable any antivirus software that is running before you start the upgrade. Also turn off any hardware antivirus features that are running. For example, the BIOS in some computers contains antivirus functionality.
In some cases, Windows XP Setup turns off antivirus software during the upgrade, but in other cases, you must turn off the software first. Most antivirus software must be updated to work correctly with Windows XP. For more information about how to disable your antivirus software, see the documentation or online help.
Uncompress any compressed drivesWindows XP works only with the compression that is included withNTFS. You must first uncompress any drives that are compressed with DoubleSpace, DriveSpace, or any other drive compression software. If you do not uncompress a drive, the data on the drive is not available in Windows XP. The data on the drive is still intact, but it is not available in Windows XP. To be able to use the data on the compressed drive, you must dual-boot with the operating system that supports the compression method. If drive C is compressed, you cannot install Windows XP. If you try to run the upgrade or the Windows XP Upgrade Advisor report, you may receive the following error message:
Run ScandiskRun the Scandisk.exe tool on all your drives before you start the upgrade. Scandisk helps prevent disk errors or file-copy errors while the Setup program is running and helps prevent extra computer restarts during the upgrade that may cause the Setup program to take longer to complete. Include a surface scan to make sure that there is not a bad sector that prevents the correct reading of a part of the drive. Because a large number of files are being read from the disk, problems with file or folder damage or bad portions on the drive can cause issues while the upgrade or the Windows XP Upgrade Advisor is running.
For additional information about using the Scandisk tool, click the following article number to view the article in the Microsoft Knowledge Base:
Run ScanregRun Scanreg.exe in Windows 98 to examine the registry for errors. Although the registry is scanned for errors automatically every time that Windows 98 starts, Scanreg may help clean up some registry damage that may have occurred. The Windows XP Setup program examines the registry during the upgrade. Therefore, damaged entries can cause problems.
For additional information about Scanreg.exe, click the following article number to view the article in the Microsoft Knowledge Base:
Remove temporary filesYou do not have to remove your temporary files. However, it may be helpful to do this. To remove your temporary files:
- Click Start, point to Programs, point to Accessories, point to System Tools, and then click Disk Cleanup.
- Select the Temporary Internet Files, Recycle Bin, and Temporary Files check boxes.
- Click OK.
