1. Start,My computer, right click on Local Disk (C:), click on properties shows the disc with used and free space available.
2. Right click on taskbar, then clicking on Task Manager brings up Physical/Kernel memory.
These are different kind of graphs. Are they showing the same thing, that is how much memory (RAM) you have and how much has been used?
My Physical memory is TOTAL -514124..AVAILABLE-100000...SYSTEM CACHE-222496.
Also, what is Kernel memory?
