Quick Answer
hwinfo64.exe is safe. It is a legitimate hardware information and sensor monitoring tool. It reads sensors, temperatures, voltages, and system data to help diagnose hardware health.
Is it a Virus?
✔ NO - Safe
Must be in C:\Program Files\HWiNFO64 or C:\Program Files (x86)\HWiNFO64
Warning
Multiple processes normal
HWiNFO64 may spawn a main app and a sensor service; both are expected when monitoring sensors.
Can I Disable?
YES
Close HWiNFO64 UI or disable startup; sensor service can be stopped if not required.
What is hwinfo64.exe?
hwinfo64.exe is the 64-bit Windows executable for HWiNFO64, a comprehensive hardware information and sensor monitoring utility. It collects data from SMBIOS, PCI, and various sensors to present real‑time temperatures, voltages, fan speeds, and more.
HWiNFO64 reads hardware data via SMBIOS/ACPI, communicates with sensors, and renders live graphs. It runs as an application and may also launch a background sensor service for continuous monitoring.
Quick Fact: HWiNFO64 supports thousands of sensors, delivering detailed reports for overclocking, thermals, and health monitoring.
Types of HWiNFO64 Process Components
- Main UI Process: Displays sensors, dashboards, and reports
- Sensor Service: Background service collecting sensor data continuously
- Logging Process: Optional long‑term data logging to file
- Update Checker: Checks for new versions and documentation
Is hwinfo64.exe Safe?
Yes, hwinfo64.exe is safe when downloaded from the official REALiX/HWiNFO site and located in the proper Program Files directory.
Is hwinfo64.exe a Virus or Malware?
The real hwinfo64.exe is NOT a virus. Malware can masquerade with similar names, so verify location and signature.
How to Tell if hwinfo64.exe is Legitimate
- File Location:: Must be in
C:\Program Files\HWiNFO64\HWiNFO64.exe or C:\Program Files (x86)\HWiNFO64\HWiNFO64.exe. Other paths are suspicious.
- Digital Signature:: Right-click the file in Explorer → Properties → Digital Signatures. Should show signer "REALiX s.r.o.".
- Resource Usage:: Initial scans use modest CPU (0-8% during active monitoring) and low memory; abnormal high usage without UI open is suspicious.
- Behavior:: HWiNFO64 should run when the UI is open or a sensor service is active; unexpected background activity without user action warrants malware scan.
Red Flags: If hwinfo64.exe is found in non-standard folders (Temp, AppData) or lacks a valid signature, or runs without starting the UI, scan for malware immediately. Beware of similarly named files like "hwinfo64x.exe".
Why Is hwinfo64.exe Running on My PC?
HWiNFO64 runs to collect and display real-time hardware data and sensor values. It may run as a standalone app or as a background sensor service when configured.
Reasons it's running:
- Active Hardware Monitoring: The user has opened HWiNFO64 to monitor temperatures, voltages, or fan speeds; the UI and service run concurrently to refresh data.
- Background Sensor Collection: The Sensor Service collects data in real-time so dashboards remain up-to-date without polling delays.
- Startup/Auto-Launch: HWiNFO64 can be configured to start with Windows, ensuring sensors are ready on login.
- Logging and Reports: If enabled, HWiNFO64 logs sensor data at intervals for later analysis.
- Update and Monitoring: The app checks for updates and keeps sensor drivers current, which may spawn background tasks.
Can I Disable or Remove hwinfo64.exe?
Yes, you can disable hwinfo64. It is safe to close the UI and you can disable startup or uninstall if you no longer need hardware monitoring.
How to Stop hwinfo64
- Close the UI: Exit HWiNFO64 from the File menu or by closing the window.
- Stop Sensor Service: In Task Manager, end the HWiNFO64 Sensor Service if running in background.
- Disable Startup: Task Manager → Startup tab → Disable HWiNFO64
- Disable Logging: In HWiNFO64 settings, turn off automatic sensor logging.
How to Uninstall HWiNFO64
- ✔ Settings → Apps → Apps & features → HWiNFO64 → Uninstall
- ✔ Control Panel → Programs → Uninstall a program → HWiNFO64 → Uninstall
- ✔ Delete leftover configuration if desired from AppData\Roaming\HWiNFO64
Common Problems: High Sensor Data Load or Missing Sensors
If hwinfo64.exe is not reporting sensors correctly or uses too many resources, try these fixes.
Common Causes & Solutions
- Too Many Sensors Enabled: Disable unused sensor modules in HWiNFO64 or reduce scan rate in Settings
- Background Sensor Service Enabled: If you don't need live logging, disable the Sensor Service in Settings
- Outdated Sensor Drivers: Update HWiNFO64 to the latest version and ensure drivers for your motherboard are supported
- Conflicting Monitoring Software: Close other hardware monitoring tools to avoid sensor conflicts
- Permission/Access Issues: Run as Administrator to access protected sensors or data
- Corrupted Configuration: Reset HWiNFO64 settings to default from File → Defaults
Quick Fixes:
1. Quick Fixes:
2. 1. Open HWiNFO64 → Configure sensors and disable unused modules
3. Set a reasonable update interval in Settings
4. Restart HWiNFO64 to refresh sensors
5. Update to the latest version from the official site
6. If issues persist, reinstall HWiNFO64
