What is paged pool and non paged pool memory?

Paged pool is amount of kernel and device driver memory that CAN spill over from physical memory into the slow page file (source). Nonpaged pool is the amount of kernel and device driver memory that must stay in physical memory. This type of memory cannot be offloaded onto the disk.

What is the difference between available and free memory?

Available is the total of standby and free memory from the Resource Monitor. (✔ ok). Free is the amount of memory that is currently unused or doesn’t contain useful information (unlike cached files, which do contain useful information).

Why is non paged pool memory so high?

A large non-paged pool size often indicates that there is a memory leak in some system component or device driver. In most cases, the reason for the memory leak described above is some problems with the third-party drivers installed in Windows. As a rule, these are network drivers.

What is RAM committed?

Commit memory is memory that has been associated with a reserved address, and is therefore generally unavailable to other processes. Because it may be either in RAM or on disk (in the swap file), committed memory can exceed the RAM that is installed on the system.

Why is so much RAM committed?
