A desktop uses the same OS as any other computer, Windows, Mac OS, or Linux. Also, I'd recommend Mac OS X if you're getting a new computer. Here's the scoop: if the computer has an  on it, it runs Mac OS. If not, it runs Windows or Linux.
Yes, Windows 7 comes with Windows Firewall in the OS itself.
No.
Macs do not come windows ,only PC's come windows so no a macbook does not have windows 7. However, I heard that Macs can run Windows as smoothly as a PC so you could probably buy windows for it.
No, it does not.
No, it does not come with Microsoft Office.
Yes
Yes, Windows 7 can run all versions of Photoshop
Windows 7 doesn't come with its own anti-virus, but it does come with something called BitLocker which can encrypt data on your computer for you so it can't be seen by others. It's available on Windows 7 Professional and Windows 7 Ultimate.
BitLocker comes as a feature part of Windows 7 Ultimate. It does not, unfortunately, come as a part of Windows 7 Professional.
Not all of them do, you need to make sure that it comes with Windows 7.
No, Windows 7 Starter does not come with Chess Titans and cannot be downloaded and installed either. Windows 7 Starter is a very basic version of windows.
