How to fix
“Windows can’t set up a homegroup on this computer” error
on Windows

Hello, I have been running into some type of problem lately. I am using Windows 10 on my laptop. I have tried to create a homegroup by using my computer multiple times but it always fails and I receive this error: "Windows can't set up a homegroup on this computer". How to make the error go away and fix things?

Homegroup appears to be a very handy feature for many Windows users worldwide. This function was invented with the release of Windows 7 and is also working on other more recent versions such as Windows 8 and Windows 10.[ref en-3] The main goal of this feature is to provide sharing between different computers that are connected to the same home network.

However, for this feature to work properly, every user who wants to use it should be a member of the created Homegroup and not only on just the same network. When this is done, people can share files, documents, and printers with each other's computers with the members that are in the Homegroup. This function is very comfortable as all the sharing work can be done remotely and does not require any additional hardware.[ref en-1]

The sharing process between members of the Homegroup is very easy and users are not even required to enter a username or password. Also, every person gets the ability to pick those files that he does not want everybody else to see and receive. This also is a very handy function as it allows protecting your private documents.

Even though the Homegroup feature is a very handy one, there are almost no programs that do not encounter problems. Some users have been complaining[ref en-2] that when they are trying to access a particular homegroup or create a new one on their computer, they start receiving the below-provided error message:

Windows can't set up a homegroup on this computer.
