Dell is advising customers that the last day to get a Windows XP systems is going to be June 18th, 2008. After this date Dell will be operating under Microsoft’s downgrade rights policy.
Per the Microsoft® Windows Life-Cycle policy, Direct OEM and Retail License Availability for Windows XP will End-Of-Life (EOL) on June 30, 2008. To meet Microsoft’s June 30 last-day-to-ship OEM Windows XP deadline, June 18 is the last time to purchase a Dell laptop, desktop, or workstation with an OEM Windows XP license.
After June 18th you have the option to purchase Windows Vista Business or Windows Vista Ultimate with a downgrade service to Windows XP Professional. If you transition to Windows Vista, don’t transition because you have to, transition because you want to!
So this may be your last chance to get a Dell with Windows XP installed unless you either go with the downgrade rights or install Windows XP yourself.
