Nexus 7 Not Showing Up on Windows 7 After Upgrade to Android 4.3

First generation Nexus 7 with Android 4.3

It was working before the last firmware upgrade.
After the upgrade the device simply doesn't show up in the file explorer.
If you go to the list of devices, it's there.
If you remove the driver, Windows will simply reinstall it automatically.
If you choose "Upgrade driver" Windows will tell you you have the most recent version.

What worked is:

1. Go to Settings --> Storage
2. Open the menu on the top left corner and select USB computer connection
3. Choose Media device

It will immediately appear :-)
It should...
