How do I know if the version of Windows 7 I have is an upgrade or full version?

by on April 29, 2010

Q: I have a dell computer running Windows XP. I have some bad virus deep in the registries (per mcaffee support) that they tried to clear for 3 days but could not. I’ve been trying for weeks but cannot. Can I format my hard drive and install Windows 7 or is the windows 7 software just an upgrade? I do have all my personal stuff backed up on an external drive.

    You can format your drive and install Windows 7 from scratch. In fact it’s really the only way you can install Windows 7 over top of Windows XP anyway. Both the “Full Version” and “Upgrade” boxed versions of 7 will work for this.

    I suggest you disconnect your external drive, and boot from the Windows 7 install disk, you can do all your reformatting/repartitioning of your C: drive from the Windows 7 setup wizard.

    If you have any concerns about any devices not working in Windows 7 you can run ‘Windows 7 Upgrade Advisor’ which is a free download from Microsoft.com
