How to control CPU Usage of ntoskrnl.exe!MiWalkPageTablesRecursively

As an IT administrator, understanding how to control CPU usage of NTOSKRNL.EXE/MIWalkPageTablesRecursively is important for maintaining a healthy IT environment. NTOSKRNL.EXE is the Windows kernel, and MIWalkPageTablesRecursively is a function of the Memory Manager in the kernel. The Memory Manager is responsible for managing the physical memory of the system, and MIWalkPageTablesRecursively is a function of the Memory Manager that processes page tables in order to manage physical memory.

When MIWalkPageTablesRecursively is running, it can cause high CPU usage, which can affect the performance of other applications. In order to control CPU usage of NTOSKRNL.EXE/MIWalkPageTablesRecursively, there are several steps that can be taken.

The first step is to identify the cause of the high CPU usage. This can be done by using Windows Performance Monitor to analyze the CPU usage of each process and identify which process is using the most CPU resources. Once the cause of the high CPU usage has been identified, it can be addressed.

If the cause of the high CPU usage is a problem with the Windows kernel or Memory Manager, then updating the Windows kernel to the latest version may help to resolve the issue. If the cause of the high CPU usage is an application, then the application may need to be updated or replaced.

In addition to updating the Windows kernel or an application, it may be possible to reduce the CPU usage of NTOSKRNL.EXE/MIWalkPageTablesRecursively by changing the priority of the process. This can be done by right-clicking on the process in the Windows Task Manager and selecting “Set Priority”. A lower priority will reduce the amount of CPU resources that are used by the process.

It is also possible to reduce the CPU usage of NTOSKRNL.EXE/MIWalkPageTablesRecursively by disabling certain features in the Windows kernel. This can be done by disabling the “Page Table Entry Scanning” feature in the Windows kernel. This feature is responsible for scanning page tables in order to manage physical memory, and disabling this feature can reduce the CPU resources that are used by the Memory Manager.

Finally, it may be possible to reduce the CPU usage of NTOSKRNL.EXE/MIWalkPageTablesRecursively by disabling certain services in the Windows kernel. This can be done by disabling services such as the Memory Manager, the Windows Memory Diagnostic Tool, and the Windows Error Reporting service. Disabling these services can reduce the CPU resources that are used by the Memory Manager.

By using these steps, it is possible to control the CPU usage of NTOSKRNL.EXE/MIWalkPageTablesRecursively and maintain a healthy IT environment. It is important to remember that these steps are not guaranteed to resolve the issue, and it may be necessary to contact Microsoft Support for further assistance.
