   Afiak, 2021(perpetual Home, Home&Business all CTR), 2021 ProPlus(MSI or   
   CTR) and later including M365 editions(Personal, Family, Enterprise, Edu)   
   after updating to the the Jan 27 2026 version/build(2601, x.20150 or   
   applicable version/build when installed/available...at this time **Do not   
   have** the necessary registry keys noted in the CVE article manual   
   workaround(editing, adding keys in the registry).   
     -i.e. assume it has not been updated and still vulnerable is the safest   
   position until known otherwise....though it is possible, and the not the   
   first occurence that a vulnerability is/was removed with other underlying   
   code exclusive of the a need to change the registry.
