I don't think Win7 alone can account for 2 GB at login, even with SuperFetch.

There were probably a few programs that run on startup (antivirus, IM, OEM-specific crapware if it's a laptop, "speed launchers" like adobe reader, updaters)

I installed a new Win7 partition last week. Yep, almost exactly 2GB memory usage at start. This was a clean Win7 Pro, no third-party crapware installed.
