Description

Microsoft is investigating a new issue preventing third-party applications from launching Microsoft Office applications or opening documents on up-to-date Windows systems. [...]

Impact

Users of certain third-party applications that rely on OLE automation to interact with Microsoft Office applications may be unable to launch Office apps or open Office documents after installing the affected Windows updates. This disrupts workflows that depend on automated Office integration, potentially impacting productivity. The issue does not appear to cause data loss or security breaches but results in application launch failures without error messages, complicating troubleshooting.

Defensive guidance

Microsoft advises affected users to open Microsoft Office applications or documents directly instead of launching them through third-party applications as a temporary workaround. Enterprise customers can contact Microsoft Support for Business to obtain a separate workaround applicable organization-wide. Microsoft is working on an official fix to be delivered in a future Windows update.
