When you are on your home network (not at a coffee shop, or airport, or library) it is safe to set your network to PRIVATE on your Windows 10 PC. You can do this for your WiFi network. There are just you and the people in your building on your network, so it is safe.

To get started doing this, click on the Network icon in the system tray in the lower right of the screen.

First double check that you are, in fact, on your HOME network that you are changing. Otherwise it is dangerous to set your network to private. Check that as shown in this picture:

Click on some blank area the background to get out of this.

Now RIGHT click on this same network icon,

It should bring up a little context menu. Left click on Open Network & Internet Settings

That should open a settings window. Double check here, again, that this is your HOME NETWORK.

If so, click on Change Connection Properties

In the resulting settings page, if it is Public, which is often the default, click Private

X out this window, and you should be all set.
