Windows 7 editions 

Thanks for editing the article Windows 7 editions. It's great to have people fix typos when they find them. That's what keeps Wikipedia great. Unfortunately, in this case I don't think there actually was a mistake. You corrected "Vista Business" to "Vista Professional". As far as I know, "Vista Business" is actually the correct name. For that reason I undid your change to the article. Please let me know if you think I've made a mistake. And please do keep correcting typos when you find them! Thanks. —
