I have HP Probook 450 G2 running windows 7 Pro x64 with a memory leak / aggressive memory usage.
After a few minutes of uptime it will expand to consume all available memory. Hitting about 2.6gb before the machine starts reporting low memory in other apps and becomes unusable.
WUDFhost.exe is a windows driver container which leads me to think it is a dodgy driver.
This machine had the problem last year and I replaced the hard drive and reloaded the OS from scratch this week and have updated it will all the MS updates.
I tried rolling back all drivers I could to see if that would help, it didn't.
I installed the latest HP Support app and let it update all the drivers.
None of it has made any differnece.
The only thing connected to the USB ports is a dongle for the mouse. The user will plug in there phone to charge, but the issue occurs regardless of the phones presence.
I ran the driver verifier with the settings as recommeneded here

and managed to get the laptop to blue screen twice.
I've tried to analyse the dump files but they are beyond my skill level.
Atttached are the two files.
Any assistance is appreciated.
