I've not been blocked from opening an admin command prompt. But I have been blocked from other things immediately after the upgrade to 2004. If Controlled Folder Access was turned on before the upgrade it goes 'hyper-active' and blocks things it shouldn't. Fortunately the fix is easy, either turn it off before updating, or after upgrading turn it off, restart then turn it back on.
