Do you still see all that memory utilized if you shutdown VM, quit Chrome and stop McAfee AV? –  Mxx Feb 18 '13 at 8:20

Enable Commit Size column on Task Manager's process tab (or just the screenshot from Memory Tab on Resource Monitor) –  Martheen Cahya Paulo Feb 18 '13 at 8:22
    
Yes I do see high physical memory usage even if I quit chrome. However I have my e-mail server which is on VM & McAfee is required to secure the Internet and LAN, as this is a live server VM. thou high memory usage was not there before 2-3 days as this system was ruining VM and McAfee at that time also. and at that time it use to show good memory usage of 5 GB around avg. So there must be some problem I think which is causing this high memory usage issue... ?? –  Rishee Feb 18 '13 at 11:01
    
@MartheenCahyaPaulo please check my comment and have added one more screenshot with Commit Size column in Task Manager's process tab. Thank you!! :) –  Rishee Feb 18 '13 at 11:03

Windows assumes that physical memory has no cost associated with using it. It makes no effort whatsoever to make physical memory free because this makes no sense. If it makes physical memory free, only one of two things can happen:

  1. That memory isn't used any time soon. In this case, the effort of making it free was wasted.

  2. That memory is used soon. In this case, the effort of making it free was harmful, as now the system simply has to undo that work to use the memory.

Modern operating systems only make physical memory free if they have absolutely no other possible choice.

If you're thinking "I need memory free now so I can use it later", forget it. You can use memory now and use it later. There's no painful tradeoff that you have to make here.

Everything is fine.

If you want a more detailed understanding of how physical memory is being used on your system, try RAMMap.

nothing is fine with his system. He has a memory leak caused by a driver ;) –  magicandre1981 Feb 19 '13 at 4:59
    
@David Schwartz May I request you to please give me some source of information to support your replay. I would like to go ahead and read that. Request you to please do not take it otherwise, as I do not mean to offend you or your statements. –  Rishee Feb 19 '13 at 20:19
    
@Rishee: You can read up on memory management anywhere. One site that tries to explain this from a commonsense angle (it's Linux specific, but the concepts are the same) is linuxatemyram. (But really, what I presented above is a reasoned argument. No source is needed. All its premises should be obviously true. For example, on typical systems Windows run on, using RAM has no cost. So it's logical Windows would understand this. And so on.) –  David Schwartz Feb 19 '13 at 20:35
    
@David Schwartz Thanks a lot!! It was very useful & Comprehensive. –  Rishee Feb 19 '13 at 20:42

You have a driver which doesn't free the memory (6GB of non paged pool). You must run poolmon from the WDK to see the causing driver. I've already posted the steps here:

Windows 8 on MSI Windpad 110W has little to no free memory after waking from sleep

Hi... I have followed the steps you said but the result of last step is not in human readable format... :( . what should I do now? –  Rishee Feb 19 '13 at 20:13
    
When I said last command I meant result of below command. findstr /s those_4_characters *.sys –  Rishee Feb 19 '13 at 20:14
    
@Rishee upload the sorted poolmon picture so that I can see the tag. –  magicandre1981 Feb 20 '13 at 5:23
    
@Rishee is the issue fixed or not? –  magicandre1981 Mar 3 '13 at 7:12
