Build 25324.1011 + ISO is out to Canary Channel

Went to grab 25324 today. No error messages, no Retry, but keeps going through partial Install (maybe 25%) and then goes back to Downloading, several times. Have never seen this behaviour with any Build previously. Maybe it will complete one of these times 🤞 I will try the ISO if & when I eventually give up on the WU method.

Check if the following registry entry is set:

Key: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\System

Entry: RunAsPPL

It's an additional protection for LSASS (read more about it here), which can be enforced by group policies as shown in the screenshot, which then blocks any changes in the Defender UI (and just shows "This setting is managed by your administrator.")

If so, that's the reason you can't change it in the Defender UI, because it it forced by Group Policies.

You can delete this entry and configure it in the UI afterwards.

Alternatively, with Windows Pro or Enterprise, you can change it using gpedit:

Nice addition, little by little getting rid of legacy settings. 👍

Too bad they still show in Control Panel and don't redirect to the new ones. 😒

Was getting bounces in the download and install. Gave up after a couple of hours and went with ISO.
