Where did my memory go?

After some months using Windows Server 2008 x64 as a desktop, and after installing some of these, one thing's for sure: memory usage starts low, but doubles with ease.

So I've decided to measure memory usage on a new laptop I've just received, a Dell Latitude D830. Here's what I got:

Description

mem

mem delta

Installed Windows Server 2008 x64

392

392

Stopped some useless services

372

-20

Installed HyperV

445

73

Stopped HyperV services

415

-30

Installed Windows File & Search services

432

17

Installed Office 2007

465

33

Removed  Groove Utility on startup

446

-19

Installed Visual Studio 2008

496

50

Stopped SQL Server services

470

-26

Installed NVIDEA driver

525

55

Stopped NVIDEA utilities on startup

500

-25

Installed wireless service

525

25

Installed Desktop service

555

30

Started Themes service

555

0

Activated Aero

615

60

Installed driver bluetooth

615

0

Installed and starting  Messenger 8.5

700

85

driver wireless

730

30

Starting Outlook

830

100

Starting FeedDemon

880

50

Update: Mobile Center: +12MB

 

Like always, we start with an acceptable 392 MB usage, but we always end up getting near 900MB with great ease. Just to get to a minimal usage. And I didn't throw a web browser here...

Here's the same list ordered dependently by memory usage:

Outlook and messenger on top, as expected. Interesting how Aero doesn't suck that much memory. And yes, search services mem can probably depend on how much you're indexing.

Throw in some Firefox and IE, some Visio, Excel and Word  docs, a Visual Studio debug session and your favorite Virtual Machine, and you'll quickly asking for the other 2GB of RAM you didn't get (yet). Oh well, nothing new here, just glad to know where did my memory go :)
