A question about how much memory my OS is using?

Hi there, please can you help. I have a brand new PC and I have 4gig of ram, in windows it shows up as 4gig of ram, which is brilliant, before I installed windows updates and all my drivers for my hardware and everything it just showed 3gigs but now it shows 4gigs, but anyways I just wondered is the OS actually using the full 4gigs or because I have windows vista 32bit ultimate is it just using 3gigs?

One of my friends said he thinks its using 3.2gigs...so I just wanted to get to the bottom of this question once and for all?

Thanks in advance,

It's only using 3-3.5gb.

Take your installed RAM, deduct the size of your graphics card and the size of your swapfile and that's roughly how much available RAM is left. Usually 3-3.5Gb.

If you want to know how much is actually in use, then have a look in the Task Manager on the Performance tab.
