TOP 10 OPERATING SYSTEM

1. Microsoft Windows 7

Windows 7 is the best OS from Microsoft I have ever experienced...
Easy to install... Crash free... Fabulous Graphics Support for HQ Games.. And more...
Windows Vista is the worst OS from Microsoft...
Very simple to install and better UI also best security.
Very good themes.
Less virus detector... And fabulous display... Maximum features And many more

2. Windows 8

This is lovely
This is friendly
This is fastest
This is best
All at once it must be on top
Fastest Microsoft operating system yet. It has more security features and adds an extra twist and extra compatibility to Windows.
It is nice...

3. Ubuntu

Ubuntu is a mixture of Windows and Macintosh. Looks like mac but shortcut keys is similar to windows. Great work. I love it
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 Vista
It really rock me. Windows os gets nothing. Haha sorry to all windows users

4. Windows XP Professional

This is all time favorite.. None other than Windows XP
Hey it's Really good because it is easy to learn & install & also it fast than other OS
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.

5. Macintosh OSX

By far one of the easiest operating systems to learn for a complete beginner (although switching from windows has a slight learning curve). Ideal for the artist and everyday user, the Mac OS is a personal favourite. The fact that it's unix based makes it quite similar to linux with very similar terminal commands. The only downside to Mac OS is the small range of games and the high price of the Macintosh computer required to run Mac OS X
Unfair to classify OSX as a single stand-alone OS and compare it to Windows as a long list of very different systems from 3.1 to whatever they're doing this week. OSX is a variant of Unix based on FreeBSD which is in turn based on BSD that predates MSDOS by a decade (~) by my recollection. Microsoft should join the rest of the world and help create a unified OS core such that each variant merely offers their own "flavoured" shell. Windows was nothing but a menu system for MSDOS. A Unified system would solve many of the problems of writing code for all computers to use.
Yea the whole reason why macs never get viruses is because hackers don't see any profit in hacking a mac, even though macs arc is 64bit or higher currently pc's hold the market shares in the US, thus being hackers will see profit in hacking a pc and get more enjoyment out of it rather than trying to waste time on a mac, and wit a pc you can do a hell of a lot more than just a mac where you can only do graphic arts, music design, and so forth, and not even good enough to run games on it, oh yea another thing bout macs is that the os is pretty much locked and simplyfied where there's rly no probs with the mac osx and if there ever is any probs that the user experiences they always run to the apple store because they don't know squat on how to resolve the issue, when pc users can fix issues on their own and not have to run to the apple store for help. So yea I think the numerical order of os'es should remain the same currently.

6. 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 MICROSOFT
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!
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!.. ;-)

7. Linux Mint

First of all "Linux Mint 15 Cinnamon" is "Free" Operating System
1)"Linux Mint Cinnamon 15" is better than "Ubantu 13.04"
2) It is best Operating System I ever used in my Life
3) It is very fast, very user friendly (Like "Windows 7"), Most secure OS
4) Inbuilt NVDIA/ATI Graphics Drivers (No need to install any drivers)

14) OVERALL BEST OPERATING SYSTEM (Linux Mint Cinnamon 15)

Mint is a easy to use operating system based on linux, reliable and great for new users. Based on ubuntu, there is a lot of software available on it

8. Android

What about Chrome OS?
Not the same as android
In a year it will be the number 3 OS
Android 4.1 is a fairly stale operating system with great customization options. Fun withgets will light your way into a a very interesting society, where you control everything. I would recommend this operating system in a heartbeat!
Android is definitely the best operating system because it is an upcoming fairly new OS that is very simple and is very safe in the way of virus protection and speed.

9. Windows XP

The best operating system I have ever used, thanks to microsoft,
It is best fastest operating system ever. It's better than windows 8
This is the best for me ever seen...

10. Fedora

The greatest! Does not crash. FREE. All services built in - web server (apache, php sql), dns server... Etc...
Fedora is definitively the best operating system out there. All software is out of the box, and with boxes, you can install multiple operating system into fedora. There is no reason to not use fedora over anything else.
Best OS and Free of Cost. Much more uptime compared to windows. Timely Updates, proper use, no crash and Boxes help to build VM under Fedora
