What Windows Driver Policy Does and Why You Might Disable It

Windows Driver Signature Enforcement is a security feature that prevents your computer from loading drivers that Microsoft hasn't digitally signed. When you turn it off, Windows stops checking whether a driver has that signature before installing it. This matters because unsigned drivers can come from anywhere — legitimate sources doing custom work, or sources that aren't trustworthy.

You might need to disable this if you're installing a driver for older hardware, specialized diagnostic equipment, or custom modifications that the manufacturer never submitted to Microsoft for signing. Some aftermarket performance parts, vintage printers, or industrial equipment fall into this category. The tradeoff is real: you're accepting a small security risk to use hardware that wouldn't otherwise work on your system.

Before you disable it, check whether the driver actually needs this step. Many older drivers work fine even with enforcement on. Contact the hardware manufacturer first — they may have an updated, signed version you haven't found yet.

Key Takeaways

  • Windows Driver Signature Enforcement blocks unsigned drivers at startup; disabling it requires restarting your computer in a special mode.
  • The most common method uses the Advanced Startup menu, which you reach through Settings or by holding Shift while restarting.
  • Disabling enforcement is temporary by default — it resets when you restart normally, so you only need to do this once per driver installation.
  • If you need enforcement off permanently, you can disable it through the boot configuration, but this requires administrator access and carries higher security risk.
  • After installing an unsigned driver, re-enable enforcement by restarting normally or by reversing the boot configuration change.

Disable Driver Signature Enforcement for One Installation

The simplest approach works for a single driver install: restart your computer into Advanced Startup mode, where enforcement is off by default. Hold down the Shift key, then click the power button and select Restart. Your computer will boot into a blue menu with several options.

Select "Troubleshoot," then "Advanced options," then "Startup Settings." You'll see a list of startup modes. Press the number key for "Disable Driver Signature Enforcement" — it's usually option 7. Your computer restarts again, and this time Windows loads without checking driver signatures.

Install your unsigned driver while in this mode. Once the driver is installed and your hardware works, restart normally. Enforcement turns back on automatically. This method is safest because it limits the window when your system accepts unsigned code.

Disable Driver Signature Enforcement Permanently Through Boot Configuration

If you need enforcement off every time you start your computer, you can change the boot configuration. This is more involved and carries more risk, so use it only if temporary disabling won't work for your situation.

Open Command Prompt as administrator. Right-click the Start menu, select "Command Prompt (Admin)" or "Windows PowerShell (Admin)." Type this command exactly: bcdedit.exe /set nointegritychecks on and press Enter. Your computer accepts this change and stores it in the boot configuration.

Restart your computer. Driver Signature Enforcement stays off until you reverse the change. To turn it back on, open Command Prompt as administrator again and type: bcdedit.exe /set nointegritychecks off then restart.

Verify the Driver Installed Correctly

After you install an unsigned driver, check that Windows actually loaded it. Open Device Manager by right-clicking the Start menu and selecting it, or by typing "Device Manager" into the search box. Find your hardware in the list — it should show the device name without any warning icons.

If you see a yellow exclamation mark or a question mark, the driver didn't install properly. Right-click the device and select "Update driver," then choose "Browse my computer for drivers" and point Windows to the folder where you extracted the driver files. If it still fails, the driver may not be compatible with your Windows version, or you may need to contact the manufacturer for a different version.

Test the hardware to confirm it works. For a printer, try printing a test page. For a network adapter, check your connection. For a graphics card or performance tool, run the software that came with it. If the hardware works, the driver is installed correctly.

Re-Enable Driver Signature Enforcement

If you used Advanced Startup mode, enforcement turns back on automatically the next time you restart normally. You don't need to do anything — just restart your computer as you normally would.

If you used the boot configuration method, you must manually reverse it. Open Command Prompt as administrator and type: bcdedit.exe /set nointegritychecks off then press Enter. Restart your computer. Enforcement is now back on.

After re-enabling enforcement, your unsigned driver continues to work — Windows doesn't uninstall it. Enforcement only blocks new unsigned drivers from loading. The driver you installed while enforcement was off stays installed and active.

When to Contact the Hardware Manufacturer Instead

Before you disable enforcement, reach out to the manufacturer's support page or contact them directly. Many companies have updated drivers that are now signed, even for older hardware. A signed driver is always preferable because you get the same functionality without lowering your security posture.

If the manufacturer is out of business or no longer supports the hardware, check community forums or driver databases like DriverPack or Snappy Driver Installer. Other users may have found signed alternatives or workarounds. If no signed option exists and you need the hardware, then disabling enforcement is a reasonable choice — just do it temporarily using Advanced Startup mode.

Some manufacturers provide driver signing services or can sign drivers for you if you contact them directly. This is less common but worth asking about, especially for industrial or specialized equipment where you're a paying customer.

Frequently Asked Questions

Will disabling driver signature enforcement slow down my computer?

No. Enforcement is a security check that happens at startup, not during normal operation. Turning it off doesn't change your computer's speed or performance. The only difference is that Windows doesn't verify driver signatures before loading them.

Can I disable enforcement just for one specific driver?

No. When you disable enforcement, it applies to all drivers until you turn it back on. However, using Advanced Startup mode limits the window — enforcement is off only until you restart normally, so you're not running with it disabled all the time.

What happens if I install a malicious driver while enforcement is off?

Your computer would load it and run it with full system access, which is why enforcement exists. This is the real risk of disabling it. Minimize this risk by disabling enforcement only long enough to install the driver you need, then re-enable it when ready. Only disable it permanently if you have no other option.

Do I need to disable enforcement if I'm installing a driver from Windows Update?

No. Windows Update only distributes signed drivers. If Windows Update has a driver for your hardware, use that instead of looking for an unsigned one elsewhere.

Will my unsigned driver work after I re-enable enforcement?

Yes. Once a driver is installed, enforcement doesn't uninstall it or prevent it from running. Enforcement only blocks new unsigned drivers from loading at startup. Your installed driver continues to work normally.
