Which PCs are eligible for the Express Upgrade to Windows Vista?
PCs provided by a participating Microsoft system builder that have Windows XP preinstalled and meet the Windows Vista system requirements are eligible. You may also purchase any OEM version of Windows XP from Newegg.com for installation on a computer that you have built, or upgraded, that meets the Vista system requirements, and also be eligible for the Express Upgrade to Windows Vista. No hardware purchase required!
Windows Vista minimum system requirements include:
A modern processor (at least 800MHz1).
512 MB of system memory.
A graphics processor that is DirectX 9 capable.
Not all Windows Vista features will be available for use on all PCs meeting minimum Windows Vista system requirements. All PCs meeting minimum system requirements upgraded to Windows Vista will be able to run the core experiences of Windows Vista, such as innovations in organizing and finding information, security, and reliability. Microsoft strongly recommends that any PC that you plan to upgrade to a premium edition of Windows Vista—in other words, Windows Vista Home Premium, Windows Vista Business Edition, or Windows Vista Ultimate—meets the system requirements for a Premium Ready PC, as set out at http://www.microsoft. com/windowsvista/getready/capable.mspx
