This is contrary to my experience in Windows 7. As under Linux, I run Win7 without swap on modern hardware, and I've had no trouble there. Which versions of Windows have you had trouble with?
XP and 7. Current rig had 32GB though I left the boot swap at 1.5GB when 8 was installed and likewise after the upgrade to 10. My understanding when researching this (long ago) was that Windows like to purpopsely put stuff on the swap even if there is free ram.
Even now, with not quite 9GB "in use" 22GB "standby" and 1G "free" the paging file is at 1.5% use with peak about 3%. Granted, that is tiny on a fixed 1.5GB file but for some reason Windows feels the need to drop about 20-50Mb in the pagefile.
