The Windows kernel is designed so that device drivers have the same privilege level as the kernel itself. But because the expectation is not enforced on x86 systems, some programs, notably certain security and antivirus programs, were designed to perform needed tasks through loading drivers that modified core kernel structures.
In x64 editions of Windows, Microsoft chose to begin to enforce the restrictions on what structures drivers can and cannot modify. Kernel Patch Protection is the technology that actually enforces these restrictions. It works by periodically checking to make sure that protected system structures in the kernel have not been modified.
It should be noted that Kernel Patch Protection only defends against device drivers modifying the kernel. It does not offer any protection against one device driver patching another. Ultimately, since device drivers have the same privilege level as the kernel itself, it is impossible to completely prevent drivers from bypassing Kernel Patch Protection and then patching the kernel.
With highly obfuscated code and misleading symbol names, KPP employs security through obscurity to hinder attempts to bypass it. Since its creation in, Microsoft has so far released two major updates to KPP, each designed to break known bypass techniques in previous versions.
Patching the kernel has never been supported by Microsoft because it can cause a number of negative effects. Because patching replaces kernel code with unknown, untested code, there is no way to assess the quality or impact of the third-party code An examination of Online Crash Analysis OCA data at Microsoft shows that system crashes commonly result from both malicious and non-malicious software that patches the kernel.
Interestingly, Symantec's corporate antivirus software [17] and Norton range and beyond [18] does work on x64 editions of Windows despite KPP's restrictions, although with less ability to provide protection against zero-day malware.
Contrary to some media reports, [ by whom? Because of the design of the Windows kernel, Kernel Patch Protection cannot completely prevent kernel patching. In January, security researchers known by the pseudonyms "skape" and "Skywing" published a report that describes methods, some theoretical, through which Kernel Patch Protection might be bypassed.
Nevertheless, Microsoft has stated that they are committed to remove any flaws that allow KPP to be bypassed as part of its standard Security Response Center process. In, the European Commission expressed concern over Kernel Patch Protection, saying it was anticompetitive.
Instead, Windows Live OneCare used and had always used methods other than patching the kernel to provide virus protection services. Retrieved 22 February Retrieved 30 July Users and IT professionals sometimes have issues after a Windows 10 migration.

In general, all such patches are delivered as Microsoft signed files which are installed on the machine and then loaded into memory.
The former is used by potentially malicious software and third party vendors to change system behavior through untested and unsupported mechanisms. The latter is a well tested process by which we deliver bug fixes to customers, for example, Microsoft providing an update to address an issue in the Windows operating system kernel.
Kernel patch protection for xbased operating systems. Send comments about this topic to Microsoft. This information applies to the following operating system: What is kernel patching? What problems are associated with kernel patching?
The Windows kernel is tested extensively before any release of the operating system to ensure a high level of quality. Because patching replaces kernel code with unknown, untested code, there is no way to assess the quality or impact of the third-party code.
Furthermore, kernel code is by its nature complex and critical to system stability, so bugs in unknown code can have a significant negative impact on system stability. An examination of Online Crash Analysis OCA data at Microsoft shows that system crashes commonly result from both malicious and non-malicious software that patches the kernel.
Kernel performance is critical to the overall performance of the operating system. When low-level system calls are intercepted and unknown code is executed before control returns to the kernel, performance becomes unpredictable.
Poorly designed unknown code can cause significant performance issues for Windows users. Patching results in unknown code executing in kernel mode, so it is increasingly an avenue of attack by malicious software.
Why was kernel patch protection implemented? What versions of Windows support patch protection? Modifications that trigger this behavior are: Modifying system service tables. Modifying the interrupt descriptor table IDT.
Modifying the global descriptor table GDT. Using kernel stacks that are not allocated by the kernel. Patching any part of the kernel detected only on AMDbased systems. Over time, patch protection will be extended to protect additional kernel resources.

Since patching the kernel is technically permitted in bit x86 editions of Windows, several antivirus software developers use kernel patching to implement antivirus and other security services. The white paper that explains the criteria we are using to help evaluate and prioritize the types of APIs that will be developed and when they will be delivered can be found here Kernel Patch Protection Criteria Evaluation Document. The free version of CCleaner doesn't bug you about paying for the premium version, nor does its interface try to trick you into looking at a sales pitch.

Note that kernel patch protection has already received routine updates at least once since the first release, but the underlying enforcement policy has not changed since the first release.
