Microsoft has acknowledged a delay in the delivery of the June 2025 Windows security updates due to an incorrect metadata timestamp affecting Windows 10 and Windows 11 systems under quality update deferral policies. The update was released on June 10, 2025, but the timestamp shows June 20, 2025, which may cause devices with deferral settings to receive the update later than expected. Microsoft has provided temporary workarounds for administrators, including creating an expedited deployment policy to bypass deferral settings. The delay only affects the timing of update availability for organizations using these policies and does not impact the quality or applicability of the update. Microsoft will not change the metadata timestamp and has confirmed that the provided workaround is the definitive resolution.
