Answer:
Microsoft Windows
Step-by-step explanation:
Microsoft Windows is an example of proprietary system software. Proprietary software is software that is owned by a specific company or individual and is typically only available for use through a license from the owner. This is in contrast to open-source software, which is freely available for anyone to use, modify, and distribute. Microsoft Windows is a proprietary operating system developed and owned by Microsoft Corporation. It is not open-source and can only be used by individuals or organizations who have purchased a license from Microsoft.
Linux, Microsoft Internet Explorer, and Microsoft Office are not examples of proprietary system software. Linux is a free and open-source operating system, and Microsoft Internet Explorer and Microsoft Office are both proprietary software programs developed and owned by Microsoft Corporation.
