Windows 7: Need Advice Installing Win 7 Upgrade

Need Advice Installing Win 7 Upgrade

Hi All -

Several months ago I puchased Windows 7 Professional Upgrade from the Microsoft Store. I previously had Win XP. The upgrade installed perfectly and Win 7 works great.

However, I am now in need of doing a clean install of Win 7 on the same PC. Is there a command line switch or any other install options available that will allow me to install my Win 7 upgrade without having to install Win XP first?

Thanks in advance for your replies,

Mike

Stick the win 7 disc in & begin the setup. At some point it should ask for XP to confirm the upgrade. I think.

Thanks Derek, I'll try it and see what happens. I knew there had to be a way to do this. All previous versions allowed you to do so.

The reply is much appreciated.

When you (correctly) boot the Windows 7 DVD to install, it will scan the HD and if it sees any other OS will pass a flag allowing use of Upgrade version key during install - even if you go on to use Custom>Drive Options to delete, repartition and/or format during install.

If you install to a clean or new HD, leave the Product Key blank during install then after install use one of the available (in case of HD failure) which Derek linked to, easiest of which is doing the quick registry workaround after install.
