Paul: Win10 Laptop Using Hard Disk As Memory!

Hi Paul, Hope you are safe during the pandemic.

As stated above, My 2015 HP laptop, Windows 10 Home Edition, 
originally with 4GB RAM and doubled by me, is still paging to the 
hard drive, and using onlyup to 3.5 GB of the 7.4 now visible and 
available.

I reduced the Page File in settings to only 100mB or some such, 
but this behavior is continuing.  

What else can I check?
