Microsoft is expanding the Windows 98 beta to include current Windows 3.1 users. If you're using Windows 3.1, please visit the Windows home page to apply for the beta.
You won't be able to navigate through the beta site unless you're using Windows 3.1, so don't bother if you've already upgraded. This beta opportunity is specifically designed so that Microsoft can test the Windows 3.1-to-Windows 98 upgrade path.
