The Microsoft Root Certificate Program supports the distribution of root certificates, enabling customers to trust Windows products. As was previously announced in March 2022, the United States Federal PKI team formally requested the removal of the “Federal Common Policy” root certificate, also known as the “G1” root certificate, from the Microsoft Trusted Root Program.
When will this happen
On May 24, the “G1” root certificate will be removed by an out-of-band update. Action is required before this date on environments which presently use this certificate.
