How do you identify a memory leak in a device driver for Windows 10 when the string is too long?

I am ruing Windows 10 on a Lenovo T440. The system has been upgraded to the latest drivers and system patches through Windows first then Lenovo's System Update app. I am experiencing, what looks to be, a memory leak. The system and compressed memory process is taking up about 250,000k. I found an article describing the process of identifying the specific driver from poolmon. I tracked it down to the ConT pool tag. When I use findstr it tells me many times that Line XXXXX is too long.

So, how do I find the driver that is taking up the memory?
