HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management

Data type Range Default value
REG_DWORD 0 | 1 0


Specifies whether user-mode and kernel-mode drivers and kernel-mode system code can be paged to disk when not in use.

Value Meaning
0 Drivers and the kernel must remain in physical memory.
1 Drivers and the kernel can be paged to disk as needed.

Tip Image Tip

Leaving this value set to 0 is useful when debugging drivers because all of the code and data is always memory resident.
