Change Network location from Public to Private in Windows 8.1

If we are using Windows 8 or 8.1 at home or at work, and others cannot access shared folders on our PCs, then maybe our network profile is set to Public as default. If we are lucky, follow this post can help us change the profile to Private to enable file sharing http://community.spiceworks.com/how_to/show/18934-change-network-location-from-public-to-private-in-windows-8.

However, on my Windows 8 or 8.1 PCs, I cannot right click on the Network icon to change the profile as instructed, so there is another way.
1. Right click on the Network icon on the notification area, click Open Network and Sharing Center
2. Click on HomeGroup

3. Click on Change network location

and choose Yes

4. Now, we can go back to the Network and Sharing Center to check our network profile, it should be changed to Private
