I am a bit confused as to why windows is saying I have got 16 gb installed ram but only 12gb total physical memory.
I will post a screenshot of my system details.

Also when I looked into task manager 2gb of memory is being used even though I have nothing running in the background. so that leaves me 10GB why is this ?

I am still confused as to why it says 16 GB installed memory but only 12 GB is showing up as total physically memory though

You probably need to check your BIOS and verify that memory remapping is enabled. See this article.
