Maximizing the amount of physical RAM makes a dramatic difference in Windows 10 performance.
A 32-bit system running Windows can accommodate up to 4 GB of RAM, and a 64-bit system can handle 128 GB -- or much more, depending on the version of Windows 10 you install and your computer's motherboard.
Why doesn't Windows use more of the free memory and less of the page file?
Does it need to leave some x amount of free ram, how much would that be? My plan is get more ram and an SSD for the main drive. Just because it is writing/reading to the page file does not mean it us using it, it may just be updating it so it can dump the memory quicker if there is a sudden demand.

In "Virtual Memory", please un-check the box "Automatically manage paging file size for all drives" (... Theres no one-size-fits-all answer to how much page file or swap space you need.
On most Windows 10 systems with 8 GB of RAM or more, the OS manages the size of the paging file nicely.There are a number of reasons to move the Windows page file to another disk.Moving the file from the partition where Windows is installed to another hard drive can improve system performance and decrease page file fragmentation.2.5 GB is typical on 16 GB systems, and 5 GB on 32 GB systems.However, the more memory installed, the smaller the paging file you need because it's unlikely the computer will use all its memory at one time.
