Enable origin-keyed process isolation by default.

Computer and userIntune-readyOriginKeyedProcessesEnabled_recommended

Supported on Microsoft Windows 7 or later

1.93.137

What it does

Enables origin-keyed process isolation for most pages (i.e., those assigned to an origin-keyed agent cluster by default). This improves security but also increases the number of processes created. Users are allowed to override the set policy value via the command-line flags or chrome://flags (both to turn this feature on or off). Setting the policy to Enabled results in most origins being isolated, even from other origins in the same site. See also the IsolateOrigins and SitePerProcess policies. Setting the policy to Disabled results in no origins being isolated from the rest of their site unless an origin explicitly asks to. Not setting the policy results in the browser determining which origins to isolate and when to isolate them.

What it writes

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.
