How much memory does Windows 7 64x use for itself?

I'm generally very picky about what my computer does - I'm disabling a lot of stuff that I don't like (i.e., different MS office, nvidia, creative stuff that tries to autorun), I constantly monitor my computer for all sorts of misbehaving programs.


My AV of choice is Kaspersky and I think I'm pretty secure from viruses because I never visit fishy sites like poker/porn, and never install programs from unconfirmed sources.


However, I have just randomly checked and it seems that after I freshly start my PC, about 1.5GB of 8GB RAM is already used up! In the Task Manager, "all user's processes" ticked of course, top users are explorer.exe at 73MB, SQL Server at 51MB and dwm.exe at 28MB. I've manually calculated total amount for all processes that are running, and came to a number of less than 400MB (had to round up everything to count only megabytes).


So, is it true that the system itself uses 1.1GB? Because I've googled and people report their PC uses only ~500MB memory when just started.


If no specific information is available, maybe someone could give me advice about how to find out what else uses RAM (except what is listed in Task Manager)? So I could track whatever is hogging that gigabyte of RAM.
