Install Allwinner Drivers on Windows 11 (Driver Signature Fix)

Q: Is disabling driver signature enforcement risky?

It temporarily lowers one layer of Windows protection while it is off. The setting resets on the next reboot, and the installed Allwinner driver keeps working. Only install drivers you trust, and restart right after the install to restore full protection.

Q: Does this work on Windows 10 too?

Yes — the same Advanced startup, Startup Settings, press 7/F7 flow works on Windows 10.

Q: Can I permanently disable driver signature enforcement instead?

You can via bcdedit, but it is not recommended. Permanent disabling weakens your PC's defenses for no benefit — the temporary method is enough, and the installed driver keeps working after reboot.

Windows 11 refuses to install the Allwinner USB driver with “Windows can’t verify the publisher of this driver software”. Here is the safe, official way to get it installed.

Why Windows 11 Blocks the Allwinner Driver

The Allwinner USB driver is not digitally signed by Microsoft. Windows 11 enforces driver signature verification by default, so it blocks the installation — this is normal and expected, not a sign the driver is malicious. The fix is to temporarily disable driver signature enforcement, install the driver, then let Windows turn the protection back on at the next reboot.

Disable Driver Signature Enforcement (Step by Step)

Open Settings → System → Recovery. Under “Advanced startup”, click Restart now.
After the PC restarts into the blue recovery screen, choose Troubleshoot → Advanced options → Startup Settings, then click Restart.
The PC restarts again and shows a numbered list. Press 7 (or F7) to select “Disable driver signature enforcement”.
Windows boots normally, but with signature checks off for this session only.
Install the Allwinner USB driver now. Follow our driver guide: Allwinner USB driver installation guide. The “can’t verify the publisher” warning will no longer block the install.
Verify the install: open Device Manager — the Allwinner device (VID_1F3A) should appear with no yellow warning. If you still see Code 10 or Code 43, see Fix Code 10 / Code 43 errors.
Restart the PC. Driver signature enforcement turns itself back on automatically. The already-installed Allwinner driver keeps working.

What If It Still Fails?

Make sure Secure Boot settings in your BIOS are not adding a second layer of blocking (rare, but possible on some laptops).
Run the driver installer as administrator (right-click → Run as administrator).
If the device is not detected at all, work through the full detection checklist before blaming the driver.
Still stuck at 7% during the flash afterward? That is a cable/port issue: fix the 7% freeze.

FAQ

Is disabling driver signature enforcement risky?

It temporarily lowers one layer of Windows protection: while it is off, Windows will not stop you from installing an unsigned driver — which is exactly what you need here. The key word is temporarily: the setting resets on the next reboot, and the Allwinner driver you installed keeps working. To be honest: only install drivers you trust from a known source, and restart right after the install to restore full protection.

Do I have to do this every time I flash?

No. You only need it once, at driver-install time. After the driver is installed and the PC is rebooted, flashing works normally with signature enforcement fully on.

Does this work on Windows 10 too?

Yes — the same Advanced startup → Startup Settings → press 7/F7 flow works on Windows 10. On Windows 7/8 the steps differ slightly, but those systems are rare for this task now.

Can I permanently disable driver signature enforcement instead?

You can, via bcdedit, but we do not recommend it. Permanent disabling weakens your PC’s defenses for no benefit — the temporary method above is enough, and the installed driver keeps working after reboot.
