(adsbygoogle = window.adsbygoogle || []).push({}); ok i am completely new to linux, and im just wondering if i should install it, what are pros and cons, also if i do can i change back to windows 7

If you don't know anything about Linux, don't even try installing it.
and no, you can't go back easily after installing Linux.

Just dual boot it,

Pros: Faster, More Secure, Great for learning more about computers
Cons: Doesn't run .exe, or many application,( but comes as a con installing them as you learn allot ).

Install ubuntu via Wubi. When you start your PC, you get an option to use Windows 7 or Ubuntu.

Ubuntu is in my opinion the easiest form of linux to use, and is the most widely supported.

Pros: Doesn't Get any viruses, malware, trogens, or any malicious software
Supported by a community
Free
Doesn't slow down over time. Either by mass overload of programs or files.
Many Distributions to choose from.
Many Free Software
Easy to use and to alter to your own specifications

Cons: PC games can't be installed unless you buy crossover
Doesn't support iTunes but there are alternatives
Doesn't run all programs made for windows


Or what you can do is dualboot both windows and linux. I used to do that but now Im using only linux

you can also download virtual box OS which will allow you to run windows xp vista or 7 inside it's own window and allow you to run any windows program. wine doesn't work on all .exe's
