(http://support.microsoft.com/kb/256986/EN-US/ )Description of the Microsoft Windows Registry
This article describes how to detect hardware on your computer without having to reinstall Windows. This may be useful if you need help with properly detecting hardware in your computer, but you do not want to reinstall the operating system.
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
You can change a registry entry, and then restart your computer so that the Hardware Detection phase of Setup runs. To start the Hardware Detection phase of Setup only, use Registry Editor to view the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersio nRight-click the SetupFlags value in this key, and then click Modify. When the Edit Binary Value dialog box opens, change the value of the first number by one. For example, you can add 1 to the first hexadecimal number in the DWORD. If the first number is 08, it would become 09, 0A becomes 0B, 0C becomes 0D, 0E becomes 0F, and so on. Quit Registry Editor, and then restart your computer. When your computer restarts, the Hardware Detection phase of Setup runs, and the SetupFlags value is reset to the original value.
