Windows on the desktop is a completely different can of worms. For example, I installed a small application last week to take screenshots of my entire screen every so many seconds and it was then that I realized the whole installation process (there is no installation process, just a simple executable with a config file in the same directory) and execution required zero root privilege. Technically, any application (at least any application that lives in the system tray) can take screenshots of the whole screen as often as it likes. You can probably imagine it doesn't even need to store it on disk. It could just do some quick computation and send it to whoever.
