[Xymon] how to tune memory threshold for Windows PS client?

For a wimpy laptop (latest Windows 10 Pro, 6 GB RAM), it goes orange pretty quick (three days or so), even though its mostly sitting idle. Is this MEMSWAP in analysis.cfg on the server that I want to tweak, or something else? What's reasonable for a Windows system like that? And does Windows grow swap automatically if needed (in which case the threshold could probably safely be higher)?
