Microsoft plans to expand the automatic activation of the Memory Integrity feature on Windows 11 devices starting in October. This security mechanism generates interest for two main reasons: its prior existence, which is not widely known, and the potential to cause side effects for certain users.
The Memory Integrity functionality (Integrity Protection) is already enabled on most modern computers. Its fundamental purpose is to prevent malicious code from running at the operating system kernel level. To achieve this, the mechanism uses a Virtualization-Based Security (VBS) process, creating an isolated environment in memory where drivers and code seeking kernel access are rigorously verified before being released.
This methodology is advantageous because it prevents malware that has compromised some component of Windows from accessing this secure space, thus preventing the execution of malicious code at the kernel level, which could worsen the problem.
Concerns regarding drivers stem from the fact that they need to operate directly at the kernel level. A vulnerable driver has the power to compromise multiple layers of system security.
Although Memory Integrity has existed for some time, having been introduced in Windows 10, it began to be implemented as standard in Windows 11 version 21H2, provided the hardware was compatible. Currently, computers come with this feature turned on by default.
However, through scheduled updates to be released starting in October 2026, Microsoft will make the feature automatically activate on PCs where it is disabled, which usually occurs on older machines.
It should be noted that this automatic activation, without user intervention, will only occur on computers that meet specific eligibility criteria, including the presence of defined hardware features and adequate performance evaluations.
The factor that makes Memory Integrity unsuitable for all PCs is that verification may fail when interacting with outdated drivers. Additionally, older processors may require the emulation of certain procedure steps, resulting in reduced machine performance.
Because of these limitations, many users, particularly gamers, choose to keep Memory Integrity disabled. If the feature is already active and there are no noticeable performance issues, it is recommended to keep it on. However, if difficulties arise, the user has the option to disable it to monitor the computer's behavior.
