Unmanaged Edge installs extensions from the Microsoft Store and nowhere else: it reads ExtensionInstallForcelist, blanks the value to [BLOCKED]<id>, and reports an invalid extension id forever after. Writing that key buys nothing and costs a permanent policy error plus a "Managed by your organization" badge, so the script now checks dsregcmd and skips Edge with the two ways round it. -Force writes it anyway.
