Force GPO deployed software to be re-installed

Had a problem with multiple Windows 7 clients not upgrading to Java 7 Update 60 correctly which left the Java app in an unusable state.  Easy enough to uninstall and re-install the software manually but for numerous clients it’s a bit of a pain.

Instead, delete the key which relates to Java in

HKLM\Software\Microsoft\Windows\CurrentVersion\Group Policy\AppMgmt

and reboot to prompt a re-install of the software via Group Policy.
