Windows 10 v1809 memory management change, not sure how I feel about this...
In v1803 and earlier, Windows 10,. upon feeling memory pressure, would compress memory and retain it in RAM until such time as the memory pressure exceeded the capability of the OS to ameliorate the memory pressure, upon which it would dump compressed memory to the pagefile.
In v1809, Windows 10, upon memory compression, appears to preemptively dump compressed memory to the pagefile long before memory pressure makes this an issue.
The upside is that system memory use stays lower overall as compressed memory is paged out to disk. The downside is, of course, increased pagefile use over time.
Now ostensibly, this is only an issue if you're using the default configuration where memory compression only kicks in when your system has reached about 75-80% memory utilization. I'm not. I have CleanMem set up as a scheduled task to run every five minutes to intentionally compress the contents of memory regardless of memory pressure Since v1809, my system's pagefile use has gotten ridiculous, especially when gaming.
What's extra annoying is that MS doesn't tell you about these sorts of changes. Granted, the vast majority of home users probably give zero shits about the minutiae of Windows memory management, but for fuck's sake MS if I'm gonna Google it at least have some documentation available.
