AMD Crash Defender user service. Na di user-mode side of AMD crash-defender filter. E no bi atiesrxx.exe (AMD External Events).

## Wetin you need know

AMD Crash Defender user service, no bi atiesrxx (AMD external events).

amdfendrsr.exe na di AMD Crash Defender user service wey dey talk to amdfendr filter. atiesrxx.exe na AMD External Events Utility. To end Crash Defender no dey stop hotplug events inside atiesrxx.

- **E safe?**: Check the running file path, signature, and publisher. Name alone no fit confirm say e safe.

  **Same as atiesrxx?**: No. Dat one na External Events

  **I suppose end am?**: Crash Defender extras dey pause

Feex tok say

If amdfendrsr dey here on AMD GPU PC, I dey treat am as Crash Defender. I no dey disable atiesrxx to "remove Crash Defender."

## Wetin bi amdfendrsr.exe?

amdfendrsr.exe na AMD Crash Defender user service, no bi atiesrxx.exe. Di filter driver na amdfendr. Dis process na di user service wey dey beside am.

## Wetin e dey do?

E dey support AMD Crash Defender make GPU hang fit dey contained. E no dey handle AMD External Events. Dat one na atiesrxx.exe.

## Wetin make am dey run?

AMD Adrenalin or OEM AMD graphics package dey installed. Intel-only iGPU PC no suppose show dis one as Microsoft file.

## Inspect the running instance

Inside Windows PowerShell, this read-only query show matching process IDs, creation times and executable paths on this PC. (pcm)

`Get-CimInstance -ClassName Win32_Process | Where-Object { $_.Name -eq 'amdfendrsr.exe' } | Select-Object ProcessId, ParentProcessId, CreationDate, Name, ExecutablePath | Format-List`

No result or a path we no fit access is inconclusive. Protected processes fit restrict access, and process IDs fit be reused. Keep personal paths local. (pcm)

Use the [file-identity guide](https://feex.it/wiki/l/pcm/software/system/verify-executable-path-signature/) to compare signatures and product metadata. A filename alone no fit establish safety. (pcm)

## E dey safe?

Usually safe wen AMD sign am

AMD-signed amdfendrsr under amdfendr DriverStore package na Crash Defender. amdfendrsr.exe wey dey inside Temp no bi am. Dis one still no bi atiesrxx.

Compare the recorded location with the actual file. A familiar folder alone no fit establish identity. (pcm)

`C:\Windows\System32\DriverStore\FileRepository\amdfendr.inf_amd64_*\amdfendrsr.exe`

- Tied to AMD Crash Defender / amdfendr
- Publisher suppose bi Advanced Micro Devices
- External Events na atiesrxx.exe

## I fit end am?

Crash Defender user service dey stop

To end amdfendrsr.exe dey stop dat user service until AMD start am again. atiesrxx.exe fit continue to run. Game hang fit come get fewer defender hooks.

## I fit comot am?

Uninstall AMD software, no bi random delete

Use AMD cleanup or Adrenalin uninstaller. No delete atiesrxx.exe make you take remove Crash Defender.

## E suppose start with Windows?

Di AMD Crash Defender user service dey start am. E no bi Startup Apps game shortcut.

## Common wahala dem

### People dey disable atiesrxx dey think say na Crash Defender

External Events na display hotplug and related AMD events. Crash Defender na dis filename.

### Filename scanners dey flag amdfendr as malware

Path and AMD signature dey decide am. Copy outside DriverStore na di case wey you suppose inspect.

## How to troubleshoot

Diagnose before you change anything wey fit scatter things.

### Reinstall Adrenalin from AMD or PC vendor

Dat one go restore Crash Defender and di filter. No copy amdfendrsr.exe enter System32 by hand.

### Confirm say no bi atiesrxx you dey look

Open file location. amdfendr.inf DriverStore na dis article. atiesrxx.exe na AMD External Events.
