Memory Integrity walls off sensitive kernel processes from that software. An attacker could use those bugs to gain privileged access to the system. Hardware drivers are pieces of software developed by the hardware vendors that enable devices to work with Windows. One use case for Memory Integrity is to protect Windows from user-mode drivers and applications that misbehave, perhaps due to an exploited security flaw. ![]() Memory Integrity (also called hypervisor-protected code Integrity or HVCI), uses Microsoft’s Hyper-V hypervisor to virtualise the hardware running some Windows kernel-model processes, protecting them against the injection of malicious code. It rolled out Core Isolation and Memory Integrity to all Windows editions in 2018. These features are a subset of virtualisation-based security features that Microsoft has offered to enterprise users since Windows 10 shipped. It uses hardware virtualisation to protect sensitive processes from infection. Memory Integrity is a feature inside a broader set of protections called Core Isolation. The advice, issued last week, should bring relief to many users of Memory Integrity, a feature designed to protect Windows computers from badly behaved drivers. ![]() Microsoft has finally clarified how users can fix a Windows security measure that has been causing hardware problems: turn it off. ![]()
