pcmark.exe

What is pcmark.exe?

pcmark.exe is the executable for UL PCMark Benchmark Suite. It runs a curated set of real‑world workloads to evaluate CPU, GPU, memory bandwidth, storage, and overall system responsiveness. The tool spawns test workers and writes results to a project folder for comparison.

PCMark uses modular workloads, combining synthetic and real‑world tasks to generate a composite score. It orchestrates test runners, collects metrics, and cleans up temporary data after each run to deliver consistent results.

Types of PCMark Processes

• Launcher Process: Main UI and test orchestrator (1 instance)
• Benchmark Worker Process: Runs individual test modules (multiple instances)
• Storage Test Process: Handles read/write benchmarks and data generation
• GPU Test Process: Renders graphics workloads and shader runs
• Memory Test Process: Evaluates memory bandwidth and latency
• Telemetry / Helper Process: Gathers results and, if enabled, uploads anonymously

Is pcmark.exe Safe?

Yes, pcmark.exe is safe when downloaded from UL's official site (ul.com/pcmark) or trusted sources.

Is pcmark.exe a Virus or Malware?

The real pcmark.exe is not a virus. Malware may disguise with similar names; verify location and signature.

How to Tell if pcmark.exe is Legitimate or Malware

1. File Location:: Must be in C:\Program Files\UL\PCMark\pcmark.exe or C:\Program Files (x86)\UL\PCMark\pcmark.exe. Any other location is suspicious.
2. Digital Signature:: Right-click the file → Properties → Digital Signatures. Should show "UL LLC" as the signer.
3. Resource Usage:: During benchmarking, CPU and disk activity spike; idle usage should remain low outside tests.
4. Behavior:: PCMark should start only when you intentionally launch a benchmark. Unexpected autostart indicates potential tampering.

Why Is pcmark.exe Running on My PC?

pcmark.exe runs when you start a UL PCMark benchmark or when PCMark is configured to run tests automatically for quality checks and system validation.

Reasons it's running:

• Active Benchmark Use: You initiated a PCMark benchmark; the orchestrator starts multiple test modules to collect metrics.
• Background Telemetry: PCMark may log intermediate results and usage data for internal validation or optional analytics.
• Startup or Scheduled Tests: If configured, PCMark can run on startup or on a scheduled interval via Task Scheduler.
• Driver or Hardware Validation: Some tests rely on current graphics, storage, and CPU drivers to ensure accurate results.
• Helper Services: UL utilities or update checks may run alongside PCMark to manage licenses and results submission.

Can I Disable or Remove pcmark.exe?

Yes, you can disable pcmark.exe. If you don’t plan to run benchmarks, close the app and remove any startup or scheduled tasks. You can uninstall PCMark via Windows Settings if desired.

How to Stop pcmark.exe

• End Benchmark Workers: In the PCMark UI, stop the benchmark or click Cancel; alternatively use Task Manager to end pcmark.exe processes.
• Close Launcher: Exit the PCMark launcher UI completely.
• Disable Startup: Task Manager → Startup tab → Disable PCMark or UL utilities.
• Disable Scheduled Tasks: Open Task Scheduler and disable any tasks named 'UL PCMark' or 'PCMark Benchmark'.
• Uninstall if Desired: Windows Settings → Apps → PCMark → Uninstall; reboot if prompted.

How to Uninstall PCMark

• ✔ Windows Settings → Apps → Apps & Features → PCMark → Uninstall
• ✔ Control Panel → Programs → Uninstall a program → PCMark → Uninstall
• ✔ Delete residual UL folders under ProgramData or AppData if needed

Common Problems: High CPU or Memory Usage

If pcmark.exe uses excessive resources during a run or on idle time:

Common Causes & Solutions

• Too Many Concurrent Tests: Run a single test module at a time or reduce parallel workers in PCMark settings.
• Background Processes Interfering: Close nonessential applications and pause other heavy tasks during benchmarking.
• Outdated PCMark Version: Update to the latest PCMark build from UL's site.
• Driver Issues: Update GPU and storage drivers; ensure Windows is up to date.
• Thermal Throttling: Ensure adequate cooling; consider lowering test intensity or using a power plan that allows higher performance.
• Storage Health: Run Disk Health checks; ensure fast SSD for storage benchmarks; defragmentation not needed for SSD.
