AMD External Events Utility and AMD Crash Defender: can you disable them?

The AMD driver installs the External Events Utility, which handles display hotkeys and FreeSync events, and Crash Defender, which collects data when the driver crashes. This tweak disables them where they are present.

In the app the switch is called "Disable AMD Driver Side Services", described there as: Disables AMD External Events/Crash Defender background hooks (no effect if not present).

Exactly what the switch changes, read from the app's source. Switching it off is what the app writes when you turn the tweak off again.

This tweak has no fixed list of registry values to print here: it works through a driver's own settings, scheduled tasks or values that differ from PC to PC (per device, per adapter or per installed game). The app reads what your PC has and changes only that.

This tweak is one-way in the app: switching it off does not put things back. Switching it off doesn't turn these services back on. Do that in Windows Services.

Changing several settings at once? The app's Make a restore point button, on every plan, makes a Windows restore point before you start.

Not recommended if you use FreeSync.

Is "Disable AMD Driver Side Services" safe to switch on?

Not recommended if you use FreeSync. The main cost: FreeSync can stop engaging and display hotplug or hotkey handling can break without the External Events Utility.

How do I undo it?

In the app this one is one-way. Switching it off doesn't turn these services back on. Do that in Windows Services.

Is "Disable AMD Driver Side Services" free in Frozen Tweaks?

It is part of Frozen Pro and Elite. You can also make the change by hand with the values on this page.
