What is psi-exe?

psi.exe is a lightweight Windows utility designed to observe, report, and diagnose running processes on a PC. It collects CPU and memory usage, startup behavior, and basic security events to help users and admins understand what is consuming system resources. It operates with a small footprint and does not modify user data.

psi.exe uses a lightweight, non-invasive monitor that samples process metrics via Windows APIs and WMI. It collects per-process CPU and memory, startup events, and basic I/O data, exporting logs for offline analysis without altering system state.

Quick Fact: psi.exe is designed to be non-intrusive, running in its own sandboxed context to minimize impact while providing detailed process telemetry.

Types of Psi Processes

Main Monitor Process: Orchestrates sampling, UI, and data aggregation
Sampler Worker: Per-dataset thread collecting per-process CPU/memory metrics
Logger Process: Writes collected metrics to local logs and archives
Scheduler: Triggers periodic sampling intervals and maintenance tasks
Updater: Checks for psi.exe updates and applies patches

Is psi.exe Safe?

Yes, psi.exe is safe when it's the legitimate file from PsiTech Ltd obtained from official sources (psiTech.com or Windows Store if provided).

Is psi.exe a Virus or Malware?

The real psi.exe is NOT a virus. However, malware may imitate names to mislead. Validate with digital signature and location.

How to Tell if psi.exe is Legitimate or Malware

File Location: Must be in C:\Program Files\Psi\ProcessInspector\psi.exe or C:\Program Files (x86)\Psi\ProcessInspector\psi.exe. Any other path is suspicious.
Digital Signature: Right-click psi.exe → Properties → Digital Signatures. Should show "PsiTech Ltd" with a valid timestamp.
Resource Usage: Normal usage is 1-8% CPU per process, 40-140 MB memory. Constant high usage when idle is suspicious.
Behavior: Psi.exe should not start without user action. Persistent background activity or network activity without a user session indicates potential malware.

Red Flags: If psi.exe is located in unusual folders (like Temp, AppData\Roaming, or System32), runs when Windows starts without consent, has no valid digital signature, or uses persistent resources, run a full antivirus/anti-malware scan and verify publisher.

Why Is psi.exe Running on My PC?

psi.exe runs to monitor process activity and provide diagnostic telemetry. It may start during boot or when you open the Psi System Process Inspector UI.

Reasons it's running:

Active Diagnostics: The tool is actively collecting real-time process telemetry to present current resource usage.
Background Monitoring: Psi monitors for anomalies in the process list, startup, and I/O patterns to alert on issues.
Startup Programs: Psi may be configured to launch on Windows startup to establish a baseline and ongoing monitoring.
Background Data Sync: It may log data locally or sync diagnostics to a cloud account if configured.
UI or Update Triggers: Background tasks or update checks can keep psi.exe running to prepare for user actions.

Can I Disable or Remove psi.exe?

Yes, you can disable psi.exe. It is safe to close or disable when not in use, and you can uninstall it if you no longer need diagnostic tooling.

How to Stop psi.exe

End Monitoring: In the psi UI, click Stop Monitoring or press Ctrl+Shift+S to end data collection
Close Application: Close the Psi System Process Inspector window
End All psi Tasks: Open Task Manager → Processes, right-click psi.exe and End Task
Prevent Startup: Task Manager → Startup tab → Disable Psi System Process Inspector
Stop Background Apps: In Psi Settings → Update, turn off automatic background data collection

How to Uninstall Psi System Process Inspector

✔ Windows Settings → Apps → Apps & Features → Psi System Process Inspector → Uninstall
✔ Control Panel → Programs → Uninstall a program → Psi System Process Inspector → Uninstall
✔ Optionally remove residual data: delete C:\Program Files\Psi\ProcessInspector and related AppData logs

Common Problems: High CPU or Memory Usage

If psi.exe is consuming excessive resources:

Common Causes & Solutions

Excessive drivers or tabs being monitored: Reduce sampling rate in Settings or disable verbose logging for specific modules
Resource-heavy monitoring: Limit the number of processes tracked or adjust thresholds for alerts
Outdated psi.exe version: Check for updates and install the latest version from psiTech Ltd
Conflicting security software: Temporarily disable conflicting security tools or adjust exclusions for psi.exe
Corrupted logs or cache: Clear local logs and cache, then restart psi.exe
Background network activity: Review network rules and disable unnecessary telemetry in Settings

Quick Fixes:
1. Open psi.exe Task Manager within the app and identify high-usage modules
2. Reduce sampling rate or disable non-essential monitoring
3. Update to the latest psi.exe version
4. Restart psi.exe and re-check resource usage
5. Review and adjust telemetry and logging settings
