Disable Adobe Collaboration Synchronizer - Adobe Acrobat Pro 2020 & Windows 11

Before I start downloading tools or editing resgistry keys, is there a simple way to keep Adobe Collarboration Syncrhonizer from firing up? It is diabled on startup. In Acrobat Pro 2020 Pereferences>Adobe Online Services I have unchecked "sync preferences across devices and document services."

 

I only use Pro 2020 and do not use any Adobe cloud services/sharing. Windows 11.

 

Thanks!

I had high fan and the corresponding high CPU usage in task manager. I could see it was Adobe but the articles are confusing on this subject. As mentioned here I killed it over and over in task manager and that showed it was causing it. I then looked for a way to stop it. I have Adobe Acrobat Pro 2020 and it is up to date. I never use it online for anything I'm aware of at least. All my files are local and backed up on One Drive, I dont "collaborate". I simply renamed AdobeCollabSync.exe to AdobeCollabSync.exe.orig. That stopped it; and after a week, many reboots and uses of Adobe, I have no issues or errors thrown. I can't guarantee anything here but its easy to reverse with a rename. It worked so far but I have no idea if an update occurs, if that ever happens on a 2020 Adobe, if it will come back. Its not an original idea you'll see it in searches but until you try it who knows its the internet.

Go to Edit > Preferences > General. Look for any options related to "Automatically check for updates" or "Background Updates" and ensure those are also unchecked. Sometimes, background processes related to updates can trigger other Adobe services.|

 

If this doesn't resolve it, the next simplest level of intervention would involve using the Task Manager to manually end the "Adobe Collaboration Synchronizer" process each time it appears. While not a permanent solution, it's a quick way to stop it without making system-level changes.

FWIW, if you're on a Mac, it's located with Preferences > Internet > Allow speculative downloading in the background.

 

Nice one Adobe.
