Prevent Toshiba Z30s upgrading from 1607 to 1709

Dear Colleagues,

It has been identified that when the Toshiba Z30 models are upgraded from 1607 to 1709 it adds a considerable time to the boot process. Further issues have been identified such as being unable to get a wireless connection.
The mandatory date for PCs to migrate to 1709 was the 25/03/2019 but I have now prevented the upgraded on Z30s.

We are currently working with McAfee to resolve the problem and will update you as soon as we have a fix or a workaround.

Please do not hesitate to log a case and pass to EUC if you have any questions

Kind Regards
Gary
