Turning Off Automatic Updates in Windows 8
By default, a Windows 8 system will automatically install updates and
reboot the system, if it deems it is necessary. You will be warned a
few days beforehand that a reboot will be necessary within a few days,
but when the time arrives, you will get only 15 minutes to save your work
before the system automatically updates. If you are someone like me who
tends to have a lot of windows open at once and who may be working on
many tasks concurrently, 15 minutes may not be enough to save all work
in progress, even if you are sitting at the computer at the 15-minute
warning so have the full amount of time to save work in progress. And,
if the 15-minute warning comes late at night, you may not even be awake
at the time and may find when you first check the system after you have
awakened that it rebooted over night and you have lost a lot of work in
progress in applications that don't autosave. To download the updates, but
control the timing of their installation yourself, take
these steps.
