"Block Flash activation in Office documents" Security Recommendation

[Philip Kluss]

It seems like the security recommendation for the "Block Flash activation in Office documents" actually does the opposite of what is intended and overrides the disabled-by-default ability to load Flash components in Office documents.

The guidance states the following:

Remediation options

Set the following registry value:
HKLM\SOFTWARE\Microsoft\Office\16.0\Common\COM Compatibility\{D27CDB6E-AE6D-11CF-96B8-444553540000}\activationfilteroverride

To the following value: 1

According to this Microsoft article [ Flash, Silverlight, and Shockwave controls blocked in Microsoft Office ], this is exactly what you'd do if you wanted to override the already disabled component.

@Philip Kluss this looks like a question for the office forum, not Microsoft Defender ATP or am I mistaken?

@Heike Ritterit is a security recommendation in Windows Defender ATP.  I would say it does belong here.   Affects your security score.  If it is enabled incorrectly we all need to know.

Hi @Philip Kluss,

Thank you for your message.

We had a mistake in checking the expected value.
the problem already solved and you should see the correct recommendation in the portal.

Thanks,
