To answer this popular question, we will assume you are on Windows 7: if you are still using Vista or XP, we recommend you to upgrade to at least Windows 7.
Although Windows 8 contains many performance improvements, feature-wise, there is not much improvement compared to Windows 7. As a matter of fact, Windows 8 or 8.1 has actually removed some features such as the ability to set up an adhoc network, which now has to be done by using third party utilities. Besides, the lack of new features, Windows 8/8.1 also comes with a heavily built metro style start screen. Although we like the way it looks, we don't really need it. We can do with a start menu, and that is evidenced by companies taking advantage of the lack of a proper start menu in Windows 8/8.1 by designing their own.
Furthermore, Windows 8 is not used as much as Windows 7 today. As a matter of fact, statistics suggest that the number of Windows XP users equal the number of Windows 8 users. What a strange statistic, wasn't Windows XP released in the early 2000s?
