Microsoft Windows and macOS are both useful operating systems. There are businesses who much prefer macOS and some that prefer Windows. Businesses that revolve around industries such as game design, art design, graphic design may opt to use macOS due to its optimization with …
Anyone with an iPhone or iPad would benefit from having a macOS-based computer. Additionally, the learning curve for a new user is much less steep than for a Windows computer. Apple has updated its OS for 20+ years, however, still maintains the same basic functionality (turn on/off, open/close apps, etc), the same cannot be said for Windows (Windows Vista, 8, 8.1, 11).
The vast majority of business applications require it. There are some equivalents available on Linux for most applications, for example Gimp as an alternative for Photoshop, or thunderbird for Outlook, but some very specific apps require it to run correctly. Wine is difficult to configure and use, and can create instability. As a result, it is pretty much always recommended.
I would rate the usability very high. Most of the world is familiar with Windows in some way. Most businesses use Windows in some form so even if someone is going from one business to another it can be an easy transition in that sense. Windows is usually compatible with most applications that can be installed to suit many different usage scenarios and needs for businesses.
Windows runs literally every piece of software I need to work. Installations are usually quick and uncomplicated, and configuration is usually quite simple, rarely requiring finding config files and editing them manually. I chose Windows only because I had no other choice, given the requirements of my job. Because I am experienced in Linux and am not afraid to dig deep for troubleshooting and configuration, Linux is preferable to me in general. Windows requires frequent updates that also require frequent reboots, and the longer you use it the more bloated it gets. If I were able to convinec my superiors to allow it, I would be running Windows 11 as a VM inside of Linux Mint or Debian.
