Hi,
Most desktop or laptop PCs come pre-loaded with Microsoft Windows. Macintosh computers come pre-loaded with Mac OS X. The operating system (OS) is the first thing loaded onto the computer -- without the operating system, a computer is useless. Is this information are true. I need more information about it?
Please help.
Thanks!
I didn't find the right solution from the Internet.
