Computers were stuck in an update loop, rebooting when system reached around 30% completed.

Instructors had to teach without access to a computer and displaying materials.

Windows Updates and Deepfreeze software conflicts.

Windows Updates were immediately suspended. All crashed systems have been manually reimaged.

This is the second instance in 12 months. The vendors are aware of the issue and have not provided solutions. Previously a script had to be created to address a conflict. Further testing will be needed to find what is causing the issue and what possible solutions can be found. Testing updates on backup systems as a sandbox and waiting a week for possible conflicts may be a consideration, but this will delay updates and maintenance.
