5. Disabling Driver Signature Enforcement

Driver signature enforcement is a security feature in Windows that prevents the installation of unsigned drivers, as they could potentially be harmful to your system. It is a workaround that can sometimes be used to install drivers not digitally signed by Microsoft or have an invalid signature. 

So, it can be used to fix the HWiNFO64.SYS Driver errors.

Note: Disabling the Driver Signature Enforcement feature can cause some security risks, so only do so if you are confident that the driver you are installing is safe and necessary.

Here's how you can temporarily disable Driver Signature Enforcement in Windows 11:

Open Windows settings, go to the ‘System’ tab, and click on the ‘Recovery’ tile on the right.

Under the Recovery options, click the ‘Restart now’ button next to Advanced startup.

This will restart your computer into Advanced Startup Options (Windows Recovery mode). Once your computer restarts, click on ‘Troubleshoot’ and then click on ‘Advanced options’.
