Hardware Reserved Memory- How to Fix this

Yesterday, When I opened Task Manger in Windows 10 to close a program, I went through the Performance tab and noticed a very strange thing. The sum of the In use and Available memory was not equal to my total physical memory(RAM). I have 8 GB of RAM installed on my system out of which 2.9 Gigs was being in use but only 3.6 gigs of RAM was available. Where the rest of 1.5 GB RAM gone? Taking a closed look at the numbers, I figured out that 1.5 GB of memory is hardware reserved. One and half gigs of RAM is a lot of memory, that is almost 20% of total memory and it was not available for use.   I am still confused about the hardware reserved memory concept, but it is not available to user and OS and hence it is complete waste of RAM. The hardware reserved memory problem looks complicated but its solution is very simple. Follow these simple steps to fix hardware reserved memory problem.
