I've been reinstalling some more robust Dell laptops and workstations in the office with Windows 7. I've been using a Dell Windows 7 Pro OEM installation DVD. After I'm done with the install, I click the "Activate Windows now" link in Control Panel / System, pay $140 to Microsoft for a license key, and I'm off to the races.
This time around, the "Activate Windows now" link failed. I got on the phone with Microsoft. They aren't selling the Windows 7 license key any more. (Why am I not surprised?) Anyway, they recommended that I buy a Windows 7 OEM key from Amazon or NewEgg. I'm happy to do so, but I want to make sure the license key I buy is compatible with Dell Windows 7 Pro OEM installation. I'd be very unhappy if my current install said, "I don't like that license key," and I had to reinstall Windows 7 from scratch using the newly purchased installation DVD. So.... Where can I find a license key that my current installation is most likely to accept?
