What is Kernel-Mode Hardware-Enforced Stack Protection?

As its name suggests, this is basically a security feature and it protects Windows OS from different attacks including Memory attacks, or Stack Buffer Overflows. Independently, Kernel-Mode Hardware-Enforced Stack Protection is of no worth. That’s the reason why, it is used in conjunction with internal security features like Local Security Authority protection (LSA).

Microsoft developers were and are still working on the security aspects of Windows for quite a long time. Back in April 2023, this tech giant introduced its users to the “Kernel-mode Hardware-enforced Stack Protection” feature. 

Note: Windows users may use this new protection only when they are using some advanced processors like Intel Tiger Lake CPU or AMD Zen3 CPU. Both these processors allow enabling CPU virtualization in the BIOS.

What causes Kernel-mode errors in Windows?

Kernel-mode errors may occur due to the presence of some incompatible device drivers. If you have recently upgraded some device drivers citing compatibility issues, you should roll back that particular driver.

2] Enable Virtualization in BIOS

With recent developments in the computer world, users may now enable CPU virtualization under the BIOS Settings. After you enable this feature, your single physical processor can work as multiple virtual processors. Several users reported fixing the “Kernel-mode hardware-enforced stack protection is turned off” error by enabling Virtualization in their system’s BIOS. 

Since this solution requires making changes to the BIOS, the steps outlined below may vary from one manufacturer to another. However, the basic idea remains the same and that is to enable Virtualization in BIOS. 

  • Shut down your computer first and wait for 10-20 seconds.
  • Press the Power button to restart your Windows PC and keep pressing the BIOS key. This key varies from one manufacturer to another, however, it usually is either Esc, F2, F12, or Del
  • Windows 11/10 will automatically boot into its BIOS. 
  • You may find this virtualization setting either under Advanced, CPU Configuration, Chipset, or Security. 
  • Once located, enable the virtualization option by turning on settings like Virtualization Technology, Intel VT-x, or AMD-V.
  • Press F10 to save the recent changes and come out of the BIOS Screen. 
  • Your device will boot normally now with virtualization enabled on it.

Go and check if the “Kernel-mode hardware-enforced stack protection is turned off” error resolves this way.
