Anyway, much like the television, virtually everyone in the developed world has heard of Microsoft, and most famously by their line of operating systems that are used all over the world for things such as industry, business, and of course home computing and entertainment.

Approximately 90% of all computers used in the world have any version of a Microsoft operating system, specifically Windows XP, Which was introduced in 2001 and is still today the most popular and used operating system today despite not being retailed anymore and having two operating systems succeed it. Personally, i prefer Windows XP to Vista and 7, Because XP , basically can run on any PC that you might want tot install it on, for example, the minimun system requirements for windows XP are as follows
(Official):
A 233 Mhz Processor,
64 MB of RAM,
Super VGA (800 x 600) or higher resolution,
1.5 GB or higher Hard disk space,
CD Or DVD Compatible drive,
A keyboard and mouse,
Sound card and speaker and/or headphones,
A Brain.
 
Now to be fair, whose PC DOESN'T have these specs?
