armsvc.exe
Also called armsvc, adobearmservice, adobe acrobat update service
Adobe Acrobat Update Service (AdobeARMservice). It is the Windows service that supports background Acrobat and Reader updates. It is not AdobeARM.exe, the updater UI/helper.
What you need to know
ARMsvc is the Adobe update SERVICE, not AdobeARM.exe UI/helper.
armsvc.exe is Adobe Acrobat Update Service (AdobeARMservice). It stays resident so updates can apply without a full UAC dance every time. AdobeARM.exe is the helper that actually checks and shows updater UI. Ending the service does not close AcrobatNotificationClient.

What is armsvc.exe?
armsvc.exe is the Adobe update SERVICE, not AdobeARM.exe. Both often live in Common Files\Adobe\ARM\1.0. The service name is AdobeARMservice. This is not Windows on ARM.
What does it do?
It hosts the Acrobat Update Service so ARM can apply patches. AdobeARM.exe is the helper. AcrobatNotificationClient.exe is toasts. AdobeCollabSync.exe is review sync.
Why is it running?
Acrobat or Reader installed the ARM service. It can run at boot. A PC with no Adobe PDF product should not keep a Microsoft copy of this name.
Is it safe?
Usually safe when Adobe signed
An Adobe-signed armsvc under ARM\1.0 is the update service. armsvc.exe in Temp is not. This is still not AdobeARM.exe.
A legitimate copy normally runs from:
C:\Program Files (x86)\Common Files\Adobe\ARM\1.0\armsvc.exe
- Service: Adobe Acrobat Update Service (AdobeARMservice)
- Helper UI: AdobeARM.exe in the same folder
- Not Windows-on-ARM and not AcrobatNotificationClient
Can I end it?
Background Acrobat updates pause
Ending armsvc.exe stops the update service until Windows starts it again. AdobeARM.exe may still be launched by a task. Notifications are a different exe.
Can I remove it?
Uninstall Acrobat or Reader
Uninstall the Adobe PDF product. Disabling only AdobeARM.exe leaves the service. Do not delete System32 files. This is not a Windows ARM binary.
Should it start with Windows?
AdobeARMservice starts as a Windows service. AdobeARM.exe is a helper the service or a scheduled task can start.
Normal resource behavior
These are contextual labels, not universal averages.

Common problems
Name looks like Windows ARM
It is Adobe Reader and Acrobat Manager service. Windows-on-ARM is the OS. Different worlds.

The service is armsvc.exe. The helper is AdobeARM.exe. Two files, one folder.
Troubleshooting
Diagnose before you change anything destructive.
services.msc > Adobe Acrobat Update Service
That maps to armsvc.exe. AdobeARM.exe will not appear as this service image.
Repair or uninstall Acrobat / Reader if ARM is broken
Adobe documents updater repair with the product. Do not copy armsvc.exe from a forum. Notification client is unrelated.
