One of my own personal favorites is the hot patching feature that allows you to patch your system binaries even if they are currently in use. By actually patching the binaries in memory, this new feature will significantly reduce the number of reboots required for hotfixes. You will still need to reboot after updating kernel-level binaries, but as always, the fewer reboots the better."
Is this technology actually being used? I still have to reboot my pc after WindowsUpdate installs new updates and I don't think we've seen a kernel update every month.
