It depends, Windows 7 Professional is just as good as any other Windows 7 version. You do get more features if you buy a more expensive version. Windows 7 Ultimate has bitlocker feature and you can choose between 35 languages for your Windows. The Professional version doesn't have this.
Professional and Ultimate editions share most of their features. However, if your needs is that of a IT expert, you might as well go for Win7 Ultimate.
Windows 7 professional and ultimate both good enough to use. But when we compare between these two windows 7 ultimate have a stylish look and many features are available in windows 7 ultimate.
i have use both and from my own experience,i think windows 7 ultimate is better than windows 7 professional.
Neither. They are both pretty un-ultimate. I would suggest Vista or XP for reliability. Windows 7 has some serious system issues that make it difficult to properly navigate through certain areas.
I have 2 laptops that are running Windows 7 ultimate, and windows 7 professional. There are no huge differences between these two operation systems. But the ultimate is better because it has some cool features that professional doesn't have.
