Here's one I didn’t see coming.

If you are trying to install or get updates for modern apps (apps obtained through the Windows Store) and the process fails, you should check to see if the Windows Firewall service is running.

You may have experienced the message before that reads: "something happened and this app couldn't be installed. Please try again." I've seen this before myself and usually after trying again it works. But, if you receive the message along with the error code 0x0073d0a, it could indicate the Window Firewall has been turned off.

You can check the Applications and Services event logs, but the easiest way to verify that the Windows Firewall is running or not is to just open the app.

Do this:

  1. Open the Search charm and search for Firewall.
  2. Choose Check firewall status.

  1. Verify the Firewall state.

  1. If it's turned off, turn it back on.
