Hello, I would like to understand something the physical memory is being used 4545mb the virtual memory is being used 7425mb If we deduct 4545mb from 7425mb we have the value of 2880mb Why is the pagefile value 0mb? Shouldn't it be something close to 2880mb? How am I using 2880mb of virtual memory and 0mb of pagefile? It's not making sense to me please help me understand this https://i.imgur.com/iULZLJE.png
