Win 7 upgrade from evaluation version

Topic

New Reply

What I would like to know (but haven’t been able to find out) is if I need to buy the same version of Win7 as my evaluation version (ultimate v.7100) and when I install it will I lose all my previous settings?
Will the same thing happen if I install a lighter version eg. Home premium?

The “official” view seems to be no.

The short version: In the case of in place upgrade, yes you must upgrade with the same version. For clean installs, no you do not. You can use whatever version you want. I had the Win 7 RC on 3 PCs. As you know the RC was an Ultimate edition. I clean installed 2 Home Premium versions and 1 Ultimate version with no problems at all.

Phil Hi and welcome

The official view is yes you must, but since you cant “upgrade” from 7100>>>>7600 you must do a clean install and you can clean install whatever version you like.

Since you have to do a clean install you will lose your settings

Hope this helps

Thanks all for your prompt replies.
Now all I have to do is decide which flavor of Win 7 I need.

it can be done, but your need to edit a file on the CD and re-burn it, so it does not check the build number of the OS
