Microsoft pauses KB5002907 update after Office license deactivations

Source Bleeping Computer

Description

Microsoft has paused the rollout of the KB5002907 Microsoft 365 update after users report that it deactivated, or in some cases completely removed, perpetual Office 2016 and Office 2019 installations. [...]

Impact

The update caused legitimate perpetual Office 2016 and Office 2019 licenses to become deactivated or, in rare cases, led to complete removal of Office installations. This disruption affects user productivity by requiring manual reactivation or reinstallation of Office. No evidence of security compromise or exploitation is reported.

Defensive guidance

Microsoft has paused the rollout of KB5002907 and is investigating the issue. Users affected by license deactivation should attempt to reactivate their Office products using their original product keys or by signing into their Microsoft accounts to select the license. In cases where Office was removed, users should reinstall their purchased Office 2016 or Office 2019 copies. No further action is recommended until Microsoft provides updated guidance.
