There's a defined list of SIDs that WDAC recognizes as admins. If a filepath allows write permissions for any SID not in this list, the filepath is considered to be user-writeable, even if the SID is associated to a custom admin user. To handle these special cases, you can override WDAC's runtime admin-writeable check with the **Disabled:Runtime FilePath Rule Protection** option described earlier.
