Kernel Patch Protection (KPP), informally known as PatchGuard, is a feature of 64-bit editions of Microsoft Windows that prevents patching the kernel. It was first introduced in 2005 with the x64 editions of Windows Vista and Windows Server 2003 Service Pack 1. [1]
Mandatory Integrity Control is defined using a new access control entry (ACE) type to represent the object's IL in its security descriptor.In Windows, Access Control Lists (ACLs) are used to grant access rights (read, write, and execute permissions) and privileges to users or groups.
The Windows kernel uses Hyper-V to prevent malicious kernel code from overwriting the CFG bitmap. [22] CFG operates by creating a per-process bitmap, where a set bit indicates that the address is a valid destination. Before performing each indirect function call, the application checks if the destination address is in the bitmap.
Another feature, titled "Code Integrity Rooting", was designed to validate the integrity of Microsoft Windows boot and system files. [4] When used in conjunction with a compatible Trusted Platform Module (TPM), BitLocker can validate the integrity of boot and system files before decrypting a protected volume; an unsuccessful validation will ...
Windows 11 is only available for the x86-64 and ARM64 CPU architectures, as Microsoft is no longer offering a Windows build for IA-32 x86 and ARMv7 systems. [1] Additionally, NTVDM and the 16-bit Windows on Windows subsystems, which allowed 32-bit versions of Windows to directly run 16-bit DOS and Windows programs, are no longer included with ...
Supervisor Mode Access Prevention (SMAP) is a feature of some CPU implementations such as the Intel Broadwell microarchitecture that allows supervisor mode programs to optionally set user-space memory mappings so that access to those mappings from supervisor mode will cause a trap.

Kernel-mode drivers on 64-bit versions of Windows Vista must be digitally signed; even administrators will not be able to install unsigned kernel-mode drivers. [20] A boot-time option is available to disable this check for a single session of Windows. 64-bit user-mode drivers are not required to be digitally signed.
