If you source a Dell OEM Windows 7 Professional Reinstallation DVD it'll automatically activate. However its a waste of time and money the ABR methods been well tested, I used to recommend it when the Digital River .iso download links were available. P.S. Windows 10 is out at the end of next month so it may be worthwhile waiting for it and then clean installing when its released.
Hi, I have an E7440 that is currently running Windows 7 (downgraded from 8.1 Pro). I'd like to do a fresh install of Windows 7, creating a separate partition for the OS during installation. Normally I just use a Windows 7 installation disk and use the COA attached to whatever laptop upon which I'm doing the clean install. Obviously, the E7440 does not have a COA. Am I right in thinking that I can just do a clean install of Windows 7 and the BIOS of the E7440 will automatically activate it for me?  Cheers for any help!
