Actually Windows can and does use NTFS transactions (TxF) in the Installer and Updater code, so the probability of non-recoverable damage should be lower (which is also my experience; power off a Linux machine during updates and you are pretty much guaranteed to have many packages with empty files, partial file trees and so on; power off a Windows machine and it probably is still fine, but sometimes you get weird issues where it can't properly reinstall/deinstall some updates to try again).
