When I did a clean install with an upgrade disk in either vista or xp It always prompted me to insert the verison before. ie a clean install of windows 7 (upgrade version) will probably require a vista disc (but not the key persay)

hopefully it will be as simples as in xp

its possible at least with the wua disc still not sure if your can use just the win7pro upgrade disc I’d think not since they are selling it but it was in xp so…

This make is sound like it can be done online and is accually a new feature in the os

I’m going to go out on a limb here and say yes unless you get the wau version again tho pure speculation

Hello Lace,

You may want to check out the system requirements before you purchase your upgrade, they vary for each version: http://windows.microsoft.com/en-us/windows7/products/upgrade. They shouldn’t require a clean install but it is wise to backup your data before upgrading.

Cheers,

Clean install? No. And I believe historically just entering the new product key has changed version and opened up the additional features.

Worst case you should be fine with an “upgrade.” Just be sure to back up anything critical beforehand, and disable things like antivirus.

Require, no, but it’s what you should do. Until 7 has been out for 6 months or so, we won’t know what problems an upgrade might cause.
