Top Ten Best Operating Systems

5. Windows XP Professional

This is all time favorite.. None other than Windows XPM+343

Why though. It's from the early 2000's and was very virus prone, and quite low performance.M+4

Hey it's Really good because it is easy to learn & install & also it fast than other OSM+268

Best hacker-friendly operating system out there. You may say windows 7 is better, but it is that windows 7 is a mix of XP and vista together. So after all, windows XP is best OS, windows related.M+254

The best Windows system I've used. As the support's finished and security a bit of a risk I've mostly switched to Ubuntu 14.04.

4. Windows 8.1

It is just awesome. It has the start button back, you can boot to the desktop, the start screen can be personalized in more ways with more tile sizes, group naming, more apps and more. The store has apps and a better look. Has a more "metro" control panel and more. IT IS GOT TO BE THE BEST OS FROM MICROSOFTM+158

A great replacement for those who hate windows 8. It is sure to be a success as it has been seen in the past!, Its preview ain't that much but what is instore is awesome!M+117

It's cool! Microsoft included a new way of personalizing, customizing and searching!.. It's free on the web!.. Try download it, and experience the "SMARTEST" version of OS that Microsoft have ever created!.. -)M+107

Its great but Windows 10 is the best OS

3. Ubuntu

Ubuntu is a mixture of Windows and Macintosh. Looks like mac but shortcut keys is similar to windows. Great work. I love itM+550

They should sell computers with Ubuntu pre-installed!
I really like the OS, but the thing that so bad is that it uses java iced tea and not java sun
But much better than windows VistaM+381
