Microsoft today began rolling out Windows 11 (22H2), the first major update to its current operating system. It will bring many interesting innovations, including default kernel isolation and memory integrity protection designed to counter malware and various types of attacks by isolating operating system processes and the device itself.
According to the available data, this feature leads to a decrease in the overall performance of the device. When Windows 11 launched last October, core isolation was disabled by default. It is clear that Microsoft has now decided to increase user security, although enabling the mentioned feature will lead to a decrease in the performance of the device, especially when playing games. The company also noted that the developers managed to partially reduce the impact of kernel isolation on performance.
Core isolation is reportedly enabled by default on new Windows 11 PCs. On existing devices, users installing the Windows 11 update (22H2) will not automatically enable the feature. Remember that the correct operation of kernel isolation requires the TPM 2.0 module, as well as enabling some additional security features. The kernel isolation feature is also present in Windows 10, but it is disabled there by default.
