The computer must be restarted before updating
With the introduction of Windows Update, we invested heavily in building not just a software delivery service, but a commitment to delivering high quality updates in a timely manner.
It took some time to get to the point where customers trust these automatic updates, and we're proud of how far we've come.
Before the Internet, updates such as service packs and "patches" were impossibly hard to come by.
Ideally, we would like all update installations to happen seamlessly in the background without a restart.For instructions, see Restore files from the Crash Plan app version 4.8.4 and later.If the update fails, i Tunes will inform the user that the device must be restored to factory settings, which would then be able to restore from a backup.The speed of each download is primarily determined by the internet connectivity of the PC, something that WU has no control over, so it is interesting to see below that the majority of update activity occurs in the first three days after release.This three-day number is a key one that I will come back to when we talk about improvements in Windows 8.
