155.0.4283.62

What it does

Setting the policy specifies a list of hostnames that bypass preloaded HSTS (HTTP Strict Transport Security) upgrades from http to https. Only single-label hostnames are allowed in this policy, and this policy only applies to static HSTS-preloaded entries (for example, "app", "new", "search", and "play"). This policy doesn't prevent HSTS upgrades for servers that have dynamically requested HSTS upgrades using a Strict-Transport-Security response header. Supplied hostnames must be canonicalized: Any IDNs must be converted to their A-label format, and all ASCII letters must be lowercase. This policy only applies to the specific single-label hostnames specified and not to subdomains of those names. Example value: meet

The OMA-URI is an inferred ADMX-backed Policy CSP candidate derived from the source ADMX file name and policy name.
Some Microsoft policies use built-in Policy CSP pages whose area names don't match the ADMX file name, so verify the candidate against Microsoft Learn before deployment.
The generated payload is incomplete because one or more ADMX element values were not supplied: HSTSPolicyBypassListDesc
