Download Visor

The hardware monitor for gamers, for Windows 10 and 11. Free forever, no ads, and nothing else bundled in the installer.

Download available very soon

We're finishing tests of the first installer on a range of PCs. The download button appears on this page the moment it's ready. Meanwhile, read the how-to guide or see what Smart Check looks for.

How to install Visor

It takes about a minute, with no bundled extras to untick.

  1. Download

    Click the button above to get Visor-Setup.exe.

  2. Run the installer

    If SmartScreen appears, click “More info”, then “Run anyway” (see why below).

  3. Allow admin rights

    Click “Yes” in the UAC prompt. Reading hardware sensors requires administrator rights.

  4. Open Visor

    On first run the app offers PawnIO for the full set of sensors. You can skip it.

Why might Windows say “Windows protected your PC”?

Windows SmartScreen warns about new programs that haven't been downloaded by many people yet or aren't digitally signed. It doesn't mean the file is harmful. Click More info, then Run anyway, to continue.

To be safe, only download Visor from https://visor.tetono.com.

System requirements

  • Windows 10 or Windows 11, 64-bit
  • .NET Framework 4.8, already built into Windows 10/11
  • Administrator rights, because hardware sensors can only be read with them
  • Internet only to activate and check a Pro license, and to download PawnIO if you choose to
  • Optional: PawnIO for low-level sensors

Settings, history and license data stay on your PC in %ProgramData%\Visor. When you uninstall, you're asked whether to delete that folder too.

Activating Visor Pro

Three ways, whichever suits you:

  • Free 7-day trial: click “Unlock Pro” in the app and start the trial. No card needed.
  • Buy in the app: click “Unlock Pro” and choose Buy. Once payment completes, Pro activates by itself.
  • Buy on the web: buy Pro for US$2.99 (on sale with the installer), copy the key from the thank-you page, then click “Unlock Pro” in the app and paste it.

PawnIO: deep sensors, always with your permission

Per-core CPU temperatures, voltages and motherboard fans can only be read through a kernel driver. Visor has no driver of its own. It uses PawnIO, a signed open-source driver that replaces the old WinRing0 driver Windows Defender flags as risky.

  • Not bundled in the Visor installer. The app asks first, then opens the official installer from pawnio.eu if you agree.
  • Without it, Visor still works: load, clocks, VRAM, drives, network and display are all there.
  • Remove PawnIO any time from Windows Settings › Apps.

Download questions

Is Visor really free to download?

Yes. The free edition is free forever, with no ads, no bundled software and no telemetry. You only pay if you choose to upgrade to Pro.

Why does Visor need administrator rights?

Windows only lets programs with administrator rights read hardware sensors such as temperatures, fan speeds and drive SMART data. Visor uses those rights to read values only. It doesn't control fans, overclock or change voltages.

Does uninstalling leave anything behind?

No. Uninstall from Settings › Apps as usual. The uninstaller asks whether to delete %ProgramData%\Visor and releases that PC's license seat. PawnIO, if you installed it, is a separate program you can remove from Settings › Apps.

Does Visor run on Mac or Linux?

No. Visor is for Windows 10/11 (64-bit) only.
