Microsoft plans to remove the HomeGroup functionality from its Windows 10 operating system. The company made the first step towards that goal in the most recent Insider Preview version of Windows 10 as it disabled it in that build.
In "a note about HomeGroup" in the release announcement of the Windows 10 Insider Build, Microsoft confirms that HomeGroup will be retired.
The company introduced HomeGroup in Windows 7 as a new option for home users to access printers, files, and media in home networks. The core idea was to assign all devices to a single HomeGroup to share access to files and printers between all devices.
It is unclear how popular the feature was and is. It is clear however that it was never the only option that Windows users had in this regard, and it was not the best either for certain use cases. You could not add Mac OS X or Linux devices to a HomeGroup for instance.
