Clean Install Windows 7 with Upgrade Media

Unless you’re a student (who are able to benefit from the massive discounts on Windows 7), the only other option is to either buy the Full version (if you’re installing on a fresh PC) or an Upgrade version if you’ve got Vista or XP already installed.

If you’re performing a clean install then buying the full version is always preferred even though it is pricy to purchase a new Operating System. But really if it is good as XP then it is a worthwhile investment and on the plus side, you’re up to date on the latest OS offerings.

Here is a saving tip! You can actually use the Upgrade version to do a clean install, saving you £££! How do you do that? Well, on a fresh PC, insert the DVD into the drive, restart your PC and let the setup process take its course. Once completed, if you try to activate your newly installed Windows 7, it will tell you that you can’t mainly because you’ve used an Upgrade version of the OS and not the Full version to install.

Ok here is the trick and it involves you getting your hands abit dirty in the Windows Registry. Make sure that there are no Windows Updates pending that would require a system reboot. If that is the case then you’re ready to go.

- Open regedit.exe with Start Menu Search and navigate to: HKLM/Software/Microsoft/Windows/CurrentVersion/Setup/OOBE/
- Change MediaBootInstall from "1" to "0".
- Open the Start Menu again and type cmd to display a shortcut to the Command Line utility.
- Right-click this shortcut and choose "Run as administrator." Handle the UAC prompt.
- In the command line window, type: slmgr /rearm
- Then tap ENTER, close the command line window and reboot.
- When Windows 7 reboots, run the Activate Windows utility, type in your product key and activate windows.

Done! You’ve just saved yourself £££ and you’ve got Windows 7 fully installed on your PC!
