What timeframe causes a noticeable memory bump? Minutes? I would recommend using the windows performance recorder to record an etl file of explorer.exe (blogs.technet.microsoft.com/yongrhee/2015/08/04/…) and then analyze it. This is not a trivial task and may require deep understanding of system calls and some tuning.

You may or may not know this: Smoking reduces your sensitivity of smell (of smoke anyway) so the issue may have persisted longer you might think. If you confront people asking if they are ok with something, they probably will answer yes (regardless whether it is true), because this is complicated field in interpersonal relations. View it from the other perspective: They value you higher than their own comfort because otherwise you would have been removed from the job altogether otherwise without dealing with the smell.
