SUMMARY
This article describes how to save your computer's original uninstall files before you reinstall Microsoft Windows.



MORE INFORMATION
When you reinstall Windows, Setup may prompt you to re-save system files if the "UninstallDir" line in the Msdos.sys file is missing or incorrect, or if the uninstall files are missing, for example, the Winundo.dat and Winundo.ini files in Microsoft Windows 98.

If you save the system files to the same location as the existing uninstall files, your original uninstall file information can be overwritten. If this occurs, you cannot use the uninstall feature to help you restore your computer's previous version of Windows.

To save your computer's uninstall file information and to restore your previous version of Windows, you must save your current uninstall files in a new location before you reinstall Windows. Decide upon the operating system you want to reinstall, and then perform the following steps:
