About the software
What is HWiNFO?
HWiNFO is a comprehensive hardware analysis and monitoring utility for Windows. It detects every component in your system and reads their built-in sensors, presenting accurate temperatures, clock speeds, voltages, and usage in a single, organized dashboard. Because it only reads data and never changes your settings, it is both powerful and safe.
Who it's for
From curious first-time users checking their PC temperatures to overclockers, gamers, and repair technicians running deep diagnostics — HWiNFO scales to every level of experience.
Why it was created
HWiNFO was built to give everyone honest, accurate insight into their hardware — the kind of detail generic tools cannot provide — so problems can be caught early and systems kept healthy.

FAQ
Frequently asked questions
Everything you need to know about downloading, installing, and using HWiNFO.
General & Safety
Yes. HWiNFO is free hardware monitoring software for personal use on Windows, with a portable option available too.
It is a read-only tool that never changes your hardware, so it is safe when downloaded from a reputable source.
Security tools sometimes flag low-level hardware utilities out of caution. This is usually a false positive; just download from a trusted source.
No. It only reads and reports data. It never overclocks, modifies firmware, or alters your system configuration.
Absolutely. Start in Summary mode for a plain-language overview, then explore the Sensors window as you grow more comfortable.
It reads directly from hardware sensors, making it one of the most accurate monitoring tools available.
It is lightweight. If you notice overhead, increase the sensor polling interval slightly for a gentler footprint.
Yes, for monitoring. It shows live clocks and voltages while you tune, though the actual overclocking is done elsewhere.
