After successful testing with the various test groups we have released Chrome 30.0.1599.101 to MD7 workstations in order to resolve critical flaws with previous versions and to provide new functionality.
The update is being distributed in a phased roll out so it will take a few days to be applied to MD7 Lab and Office workstations and will only install when the workstation is at the ctrl+alt+del screen.
MD7 Lab machines are currently being updated and the update will start being applied to Office machines from next week.
In order to test the version of Chrome that is installed on your workstation, start Chrome and check the version number.
