Troubleshooting HomeGroups in Windows 7/8
I previously wrote an article about setting up and configuring a Windows HomeGroup. It’s a fairly simple process and most people will have no trouble getting it to work. However, as with any complicated feature of Windows, things can go wrong!
One of the biggest problems is that people simply can’t add a Windows computer to a HomeGroup! HomeGroups are different from Workgroups because they are meant to make networking between Windows 7/8/10 computers super easy. Workgroups are what you had to use to share data between Vista and XP computers, although you can add an XP computer to a HomeGroup as well.
In this article I will try to discuss in detail all the different reasons why you might not be able to access your HomeGroup. If your problem is not solved below, please leave a comment and I will try to help you out.
