During setup, Windows 10 asks you which network type you want to set for the current network connection. Once you set it as private, Windows 10 automatically shows the HomeGroup icon in the navigation pane of File Explorer. If you have no use for the HomeGroup feature and don't wish to see its icon, here is how to disable it and remove HomeGroup from Windows 10 File Explorer.

The easiest way to get rid of the HomeGroup icon in Windows 10 File Explorer is to disable this feature. All you need to do is stop and disable the HomeGroup Provider service.
Do the following:
1. Press
Win + R shortcut keys to display the Run dialog.
services.msc

File Explorer app. The icon will disappear, but HomeGroup will continue to work.You can still access it by typing this in the Run dialog:
