We have noticed that, but are not currently planning to update this temporary check,
It is worth noting that Microsofts language states that this version is “protected from this vulnerability”, which is curiously different language from stating “not affected”. The listed mitigation also make reference to Wordpad, which is a base Windows component.
The current temporary check is essentially functioning as informational, highlighting where there may be risk present.
I am hopeful (but not holding my breath) that Microsoft will release a patch this coming patch Tuesday which should clear everything up. When this happens we will remove this temporary check, and replace it with a fully accurate check taking all this into account according to the guidance provided by Microsoft when they release the patch.
