Unblock regression testing for 1.2.150-beta1

[SubPointSupport]

Currently, regression testing is blocked due to the recent windows security updates. A bunch of metabox built VMs aren't available via RDP. Seems to be caused by May 2018 security update.

Starting in the May 2018 Security update we are enforcing the March 2018 CVE-2018-0886.
