Quick Answer
pcmark-agent.exe is safe. It is the background component that coordinates PCMark benchmark runs, collects subsystem metrics, and communicates results to the PCMark UI or UL cloud services.
What is pcmark-agent.exe?
pcmark-agent.exe is the background agent for UL's PCMark benchmarking suite. It orchestrates test workloads, gathers performance metrics from CPU, GPU, storage, and memory subsystems, and relays results to the PCMark frontend or UL cloud for reporting and analysis.
This architecture enables isolated benchmark workloads, reduces cross-test interference, and allows centralized reporting. The agent runs with the user or system account and starts only as part of a PCMark workflow.
Quick Fact: PCMark benchmarks provide a standardized score across CPU, GPU, storage, and system tasks. The agent ensures tests start in the correct sequence and results remain repeatable across runs.
Types of PCMark Processes
- Agent Service: Background Windows service that coordinates PCMark workloads and data collection
- Benchmark Runner: Executes PCMark workloads, measures timing, and records resource usage
- Scheduler/Reporter: Schedules benchmark runs and reports results to UI or UL cloud
Is pcmark-agent.exe Safe?
Yes, pcmark-agent.exe is safe when it is the legitimate file from UL LLC located in the official PCMark installation folder.
Is pcmark-agent.exe a Virus or Malware?
The legitimate pcmark-agent.exe is not a virus. Malware can counterfeit file names; verify signing and location.
How to Tell if pcmark-agent.exe is Legitimate or Malware
- File Location:: Must be in
C:\Program Files\UL\PCMark 10\pcmark-agent.exe or C:\Program Files (x86)\UL\PCMark 10\pcmark-agent.exe. Any other location is suspicious.
- Digital Signature:: Right-click the file in its folder -> Properties -> Digital Signatures. Should show "UL LLC" as the signer.
- Resource Usage:: Normal usage is 2-8% CPU and 50-150 MB memory per active test. High sustained usage outside benchmarks is suspicious.
- Behavior:: pcmark-agent.exe should start with a PCMark session and terminate when the test completes. Running constantly without tests is a red flag.
Red Flags: If pcmark-agent.exe appears outside the PCMark install path (e.g., C:\Windows or AppData), runs without a PCMark session, or lacks a valid digital signature, scan the system with a trusted antivirus.
Why Is pcmark-agent.exe Running on My PC?
pcmark-agent.exe runs when a PCMark benchmark is started, scheduled, or configured to run in the background. It coordinates test workloads, collects subsystem telemetry, and communicates results to the UI or cloud services for scoring.
Reasons it's running:
- Active Benchmark Run: A PCMark test is actively executing; the agent coordinates workloads, captures timing, and logs results.
- Scheduled Benchmark: PCMark is configured to run automatically on a schedule or on system events, triggering the agent.
- Background Data Sync: The agent may synchronize results with UL cloud services or the PCMark UI after tests complete.
- Initialization or Update Check: After an update or at startup, the agent verifies test assets, rules, and signatures to ensure integrity.
- User Sign-In or System Startup: On sign-in or Windows startup, the agent can launch to prepare the environment for upcoming benchmarks.
Can I Disable or Remove pcmark-agent.exe?
Yes, you can disable pcmark-agent.exe. Disabling stops automatic benchmarking, scheduled runs, and cloud reporting; you may lose data and access to automated scores. You can uninstall PCMark to remove it entirely.
How to Stop pcmark-agent.exe
- Disable Automatic Benchmarks: Open PCMark settings and turn off scheduled benchmarks or background testing.
- Disable Windows Startup: Open Task Manager (C:\Windows\System32\Taskmgr.exe) > Startup tab > disable PCMark Task.
- End Active Tests: In PCMark UI, stop any running benchmark; if not open, end pcmark-agent.exe from Task Manager.
- Prevent Background Sync: In PCMark settings, disable cloud or local network result syncing.
- Uninstall PCMark: Windows Settings > Apps > PCMark 10 > Uninstall
How to Uninstall PCMark
- ✔ Windows Settings -> Apps -> Apps & Features -> PCMark 10 -> Uninstall
- ✔ Control Panel -> Programs -> Uninstall a program -> PCMark 10 -> Uninstall
- ✔ If you switch to another benchmark suite, ensure to remove remaining UL components if desired
Common Problems: High CPU or Memory Usage
If pcmark-agent.exe uses excessive CPU or memory or fails to start, try these PCMark-focused troubleshooting steps.
Common Causes & Solutions
- Too Many Concurrent Benchmarks: Limit concurrent workloads; ensure only necessary tests run to prevent CPU contention.
- Background Data Sync Enabled: Disable cloud syncing in PCMark preferences to lower network and CPU load.
- Outdated PCMark Version: Update to the latest PCMark release from UL to fix performance regressions.
- Large Data Sets or Hard Drive Bottlenecks: Run tests on faster storage or reduce data set sizes in the workload configuration.
- Aggressive Power Settings: Set Windows power plan to Balanced or High Performance to ensure stable CPU behavior during tests.
- Malware Misidentification: Run a full antivirus scan and verify pcmark-agent.exe originates from UL and resides in the PCMark install folder.
Quick Fixes:
1. Open PCMark Task Manager or Windows Task Manager and identify the active workload.
2. Close unnecessary benchmarks or pause heavy tests to reduce CPU usage.
3. Clear PCMark caches and reset test data if required.
4. Update PCMark to the latest build.
5. Disable verbose logging in PCMark settings to reduce memory usage.
6. Restart pcmark-agent.exe or the PCMark app.
Frequently Asked Questions
Is pcmark-agent.exe part of the PCMark benchmarking suite from UL?
Yes. pcmark-agent.exe is the background agent that coordinates PCMark benchmark runs and data collection as part of UL's PCMark software.
Why is pcmark-agent.exe running when I haven't started PCMark?
It may run if a scheduled benchmark is configured or if PCMark is set to run automatically at startup or user sign-in.
Can I disable or uninstall pcmark-agent.exe without breaking PCMark?
Disabling can stop automated benchmarks and reporting; you can still run PCMark manually. Uninstalling removes the component entirely.
Where is pcmark-agent.exe located on a typical PCMark install?
Typically under C:\Program Files\UL\PCMark 10\pcmark-agent.exe or C:\Program Files (x86)\UL\PCMark 10\pcmark-agent.exe.
How do I update PCMark to ensure pcmark-agent.exe is current?
Open PCMark and use Help > Check for Updates, or download the latest PCMark installer from UL's site and install.
