Windows – How to identify which process committed memory

memoryprocess-explorervirtual-memorywindows

My system runs high on committed memory (out of 8GB RAM + 2 GB page file 85% memory is committed). Physical usage is at some 65%.

How can I identify what process(es) is allocating most of the committed memory? I understand that memory can be shared among processes. So far I've used VMMap to show committed memory but this is on a per-process base and doesn't take pagefile-backed sections into account.

PowerShell Solution

1. Get top 10 processes using the highest amount of Virtual Memory

Get-Process | Sort PagedMemorySize-Desc | Select Name, PagedMemorySize, VirtualMemorySize -First 10

Output Example

Name                  VirtualMemorySize PagedMemorySize

2. Get sum of all committed Virtual Memory

Get-WmiObject win32_operatingsystem | Select @{L='commit';E={($_.totalvirtualmemorysize - $_.freevirtualmemory)*1KB/1GB}}

Output Example
