Long the standard operating system for businesses, Microsoft Windows remains the most popular OS. Windows XP was dominant in business for years, but Microsoft stopped supporting it in 2014. The computer giant continues to push Windows 10, which was released in 2015, as the fresh, new OS.
Because Windows, in all its varieties, is so widely popular, you are less likely to have compatibility issues when sharing files with other organizations. And the familiar interface means that there will be less time wasted on learning a new OS. Windows also offers the largest library of commercial software and gives you access to a large amount of freeware and shareware.
You'll have more options for hardware with Windows than with any other operating system. Drivers are easily available, and you can pick and choose your various components for your PC itself.
Unfortunately, maintenance-free operation is not one of Windows' strong points. This is due to the vast variety of possible hardware and software options, which makes testing all configurations impossible. Crashes are therefore more frequent than on other operating systems. To avoid OS freezes, restart your system once a day.
Windows is inherently insecure. It is highly susceptible to viruses and other malware. The sheer number of programs written to compromise Windows computers is immense. Windows users have less open source software available to them, compared to users of OS X.
Bottom Line: If security, content creation, and access to open source software are not your first concerns, choose Windows 10. You'll be on the same page as the majority of other businesses.
