Second, you shouldn't be running any proprietary binaries unsandboxed with Internet access. My standard use of Windows is to install a fresh VM, install whatever software(s) I want, kill all network access but for my local Samba server, and then do my work. Lack of updates that pull the rug out from under me is a feature, and when there are features I want it's easy enough to repeat the installation process while watching TV or whatever.

That being said, a small file size doesn't mean anything in the case of most cracks/keygens because you have to give them admin access to your system. Which means it can download and install anything it wants in the background.
