Uninstalling updates quietly could be a security risk because malicious software could quietly uninstall an update in the background without user intervention.

Solution
NOTE: Microsoft has acknowledged the issue was caused by the Microsoft June 9th update and they are also working on a resolution (as mentioned in the “Known issues with this release” section of the affected KBs above) and will be included in a future Windows update.
Additionally, the CDM team has identified the component in conflict with the update and are working hard in attempt to resolve the issue given the critical nature and its impact to our customers, coupled with the lack of a timeline on the update from Microsoft.
We believe the update will be delivered in CDM 26.2.0 (target release early July, 2026). Further updates, including progress and expected timelines, will be communicated as they become available.
