Below you may find the list of Windows updates affecting POA provisioning.

The Parallels Operations Automation team uses the following testing and publishing method for Windows security updates.

All internal testing environments used by the QA and Development departments are configured to install all Windows security updates as they arrive. This is done using a pre-configured WSUS policy.

If any update affecting provisioning is found during these tests, it will be included in this KB.

If you install updates and they affect the live provisioning system, then a support case should be opened. The support team will analyze the case, and the update will be included in this KB article if it is determined to affect provisioning.

Please also refer to the Microsoft Windows Updates supported by POA article, which contains the list of Windows updates checked by POA QA and Development teams in the past, along with testing statuses.
