    according to this chart I can’t upgrade from vista ultimate to windows 7 professional. is this true? I purchased the upgrade a couple weeks ago. does this mean I have to return it and purchase a full copy of windows 7 ultimate. after using vista ultimate I found I didn’t need the extra stuff and want to just go with a professional version.

    It’s true as the chart is released by Microsoft two days back only.

    You may not be able to do an in-place upgrade from Vista Ultimate to 7 Pro, but you should be able to do a clean install of 7 Pro by backing up all your files to a separate hard disk. It’s a bit more work, but at least you won’t have to return anything (especially good if you bought the upgrade when it was on sale like I did). I always do a clean install, no matter what, anyway. Hope you haven’t canceled your order :)
