Ah...the joys of using a Beta OS [that's actually what Windows 10 really is] ...
One issue many people have [finally] discovered is that EVEN WITH what people assume is 'enough' actual ram in a system Windows will always want and expect a Page File to be available. Yes, It's had to imagine an OS getting upset with 32 gig of DDR4 of high quality ram [as my machine has] but it does.... and I'm not even using a Beta OS .
Step one is to always allow the OS to manage the Page File size no matter how much physical ram the system has.
Step two is to [sadly] try to restrict how the OS controls its updating process so as to avoid [forced] inherent instability of the beta/update process.
Microsoft did its users a gross disservice by requiring users to accept their system of updating whether they liked it or not, thus potentially introducing as much 'bad' as they were anticipating 'good'.
