Nexus 7 Not Visible in Windows Explorer

[Scriv13]

Suddenly, my Nexus 7 is not visible in my Window Explorer. I run Windows 8.1 with the latest updates. All was fine until the latest update. My PC registers that my Nexus has been connected, it shows in the system tray and in system devices, it just isn't visible in Windows Explorer any more. I have a Windows 7 netbook and all works fine on it. Can anyone help.

Microsoft has reported that they have pulled 4 recent 8.1 updates due to issues, you may want to remove your recent updates or run  Windows System Restore to a point before the issue occurred.
