microsoft windows vs macintosh
Apple Mac OS X and Microsoft Windows are two of the most widely used desktop operating systems. Apple's Mac OS X is more commonly known as just simply: "OSX" and is developed by Apple Computer for their own line of PCs, often referred to as "Macs." Windows is developed by Microsoft for any PC (including Apple's).
Releases

OS X and Windows both have a long line of releases in their history. The X in OS X stands for 10, signifying the 10th major release of the Mac operating system. Within the Mac OS X line-up, there have been incremental sub-versions named after felines. Windows began with 1.0, following the numeric system until 3.1 and then switched to NT4. Since then, Windows 95, Windows 98, Windows Me, Windows XP, Windows Vista, and Windows 7 have followed for personal computing, while others, including Windows 2000, Windows 2003, and Windows 2008 were released as enterprise operating systems.

Market Share

The percentage of the market held by either OS is always going to be a murky, unclear answer. According to one source, Windows has a market share of 91.8% compared to OS X with 7.3% [1]. While other sources may claim only 5%, or 3% for OS X depending on how they look at the data. Although the iPhone does run Mac OS X, some do not count it as such in their market share research. Also, sales numbers do not necessarily reflect the true popularity of Windows as most new PCs come with Windows pre-installed, but some users may opt to install a different OS after purchase.

• Malware
Apple touts this feature as an advantage over (pre-Vista) Windows: "On a Windows PC, software (both good and evil) can change the system without your even knowing about it."

Windows Vista recently started to focus more on security by implementing a stricter user-permission policy, but many users feel that the strict policy is more annoying than useful.

Hence, there is no architectural advantage in security between Mac OSX and Vista concerning this point.
• Viruses
Developers often capitalize on Windows' large market share and significant vulnerabilities when creating viruses and other malicious software. Some counts place the number of Windows/MS-DOS viruses at over 50,000. In the past, Microsoft's solution to this problem was insufficient.

Infection of Macs running OS X is extremely rare, and there has never been a large-scale infection of computers running OS X. The latest version of Mac OS X added sandboxing to improve protection against malware and trojans, but it cannot protect against all possible applications users can install.
• Patches
Both Macs and Windows have patches and/or updates provided online by Apple and Microsoft, respectively. Through one simple button-click change in the System Preferences this can be on or off, to differing degrees. Ever since the release of Mac OSX 10.1 on September 25, 2001 as a 'free update' to version 10.0, Macs can download these automatically or the [owner or administrator] user has the option of accepting these downloads or not: "New software is available for your computer. If you're not ready to install now, you can use the Software Update preference to check for updates later." In Windows XP and Vista, the user has the option of turning automatic updates on or off as well.
