Yes, it does (and even more than 2 GBs of RAM), who knows why. But checking for updates doesn't take more than 5 minutes for me when it is done automatically, if I (have the time to) check for updates manually it usually takes less than 30 seconds! I don't know why this difference exists, however if I try to check manually for updates and the system has started doing it already the procedure takes longer. I have Windows Update Agent 7.8.9200.16924 from Windows Update's self autoupdate.
