What Is Adobe Collaboration Synchronizer? Is It Safe to Disable at Startup?

What Is Adobe Collaboration Synchronizer?

Adobe Collaboration Synchronizer is a background Adobe component used by some Adobe apps for collaboration-related tasks, such as syncing shared review or document workflow data. It is not a core part of Windows, and it is not required for your PC to boot.

If you use Adobe Acrobat, Creative Cloud apps, or shared review features, this process may appear in the background even when you are not actively editing a file. On many systems it starts with Adobe software rather than as a standalone app you open yourself.

Is It Safe?

Usually, yes. If the file is really Adobe's, it is a legitimate Adobe background process.

Because malware can use familiar names, verify it if anything looks unusual. In Task Manager, right-click adobecollabsync.exe and open its file location. A real copy should be inside an Adobe program folder, not in a random Downloads, Temp, or user AppData path. Then check Properties > Digital Signatures and confirm the signer is Adobe Inc.

If the file is unsigned, in an odd folder, or keeps returning after removal by security software, treat it as suspicious and investigate it instead of assuming it is safe.

Should I Disable It at Startup?

For most people, yes, you can disable it at startup if you do not rely on Adobe collaboration or review features every day.

Disabling it should not stop Windows from working, and Adobe apps usually still open when you launch them manually. The trade-off is convenience: Adobe may take a little longer to load certain background features, or collaboration-related prompts and sync actions may not be ready until the app starts.

Keep it enabled if you regularly use shared reviews, cloud-linked document workflows, or your workplace depends on Adobe background services being ready after sign-in.

Why Is It Using High CPU or Memory?

Short bursts of activity can happen after sign-in, after Adobe updates, or when Adobe apps are syncing data. That is normal if usage drops again.

If CPU or memory stays high for a long time, common causes include a stuck sync task, damaged Adobe app data, repeated sign-in checks, or another Adobe component waiting on it. Try closing Adobe apps first, then restarting the process or restarting Windows. If the issue keeps coming back, update or repair the related Adobe app.

If usage is extreme and the file location or signature does not look right, investigate it as a possible impersonator.

How to Disable or Remove It

If it appears in startup, disable the startup entry rather than deleting files by hand.

On Windows, you can check Task Manager > Startup apps or Adobe's own settings if the entry is managed by Creative Cloud or Acrobat. Some Adobe components are also started by scheduled tasks or app-specific background services, so the exact startup source can vary.

If you no longer use the related Adobe software, uninstall that Adobe app through Settings > Apps. That is safer than removing Adobe files manually.

Where Kudu Helps

Kudu can show whether Adobe Collaboration Synchronizer is actually set to launch at sign-in and where that startup entry comes from. In Startup Manager, you can disable the entry without deleting the app.

If the process is using too much CPU or memory, Performance Monitor shows the live impact and lets you match the running process to its startup item. If the file looks suspicious, Malware Scanner can help check for persistence and quarantine threats.
