How to find source of memory leak in Windows 7?

Solution 1:

The high memory usgae comes from a high Page table usage. To see which processes use it, install the Windows Performance Toolkit, open a command prompt as admin and run this command:

xperf -on ReferenceSet -BufferSize 1024 -MaxFile 512 -FileMode Circular  && timeout 5 && xperf -d MemUsage.etl

Open the MemUsage.etl with Windows Performance Analyzer (WPA.exe), drag and drop the graph "ResidentSet" from the left graph list to the analysis pane:

Now move the "Page Category" column to the left side and expand the "Page Table" entry:

Here you see the processes which have the high pagetable usage. On the right site (after the blue line), you see page table memory usage in MB for each process.
