That's probably one of my most hated things about Windows. In OS X it's mostly drag and drop, and even when you have to install something, it usually doesn't require a restart.
Its incredible that people put up with constant rebooting. In Windows, install a driver, reboot. Install a program, reboot. Change some settings, reboot. As for uninstalling things... more reboots! I wonder if Microsoft's opinion of this is: It's not an annoyance/sign of our technical deficiencies, its a feature! 
As for drag and drop installing and uninstalling, that has got to be one of the most intuiative designs, though I personally prefer the Linux way of doing things (online software repositories + installer/manager).
C. P. U. Its not a big processor... Its a series of pipes!
