INTRODUCTION

This article contains a list of Microsoft Knowledge Base articles that you can use to help troubleshoot issues that you may experience when you try to upgrade the current version of Windows to Windows Vista.

Note Before you upgrade a computer to Windows Vista, we recommend that you use the Windows Upgrade Advisor tool to help determine whether the computer can run Windows Vista successfully. For more information about how to obtain the Windows Upgrade Advisor, visit the following Microsoft Web site:
http://www.microsoft.com/windowsvista/getready/upgradeadvisor/default.mspx (http://www.microsoft.com/windowsvista/getready/upgradeadvisor/default.mspx)
Windows Vista Upgrade Advisor scans the computer and creates a report of all known system, device, and program compatibility issues that may exist. The Windows Vista Upgrade Advisor also lists recommendations about how to resolve any compatibility issues that may exist. Additionally, you can use the report that the Windows Vista Upgrade Advisor generates to help select the edition of Windows Vista that best suits the way that you want to use the computer.
