Windows 8 improves things by giving you a three-day grace period to restart your computer, although it no longer displays this information on the desktop.
After installing updates, you’ll see a notification on your welcome screen asking you to reboot.
Patches for Windows could show up at any point in the month.
From here, you can also choose whether you want to receive recommended updates (updates that aren’t as critical for security), update other Microsoft products in addition to Windows itself, or see notifications about new Microsoft software, such as Bing Desktop.
If you want to see a Windows 7-style notification on your Windows 8 desktop, you could install the free Windows Update Notifier utility.
If you don’t reboot in three days after installing updates, the nagging and automatic reboots will start.
While Windows Update can be obnoxious, it keeps your computer secure and is well worth using.
If you notice this, you can uninstall updates from the Windows Control Panel.
To open the Windows Update Control Panel tool, press the Windows key on your computer, type “Update” without quotes, and click the Windows Update shortcut that appears.
On Windows 8, you’ll have to click the Settings option before you see the Windows Update shortcut.
This allows system administrators to schedule updates all at once.
However, if a security flaw is being exploited in the wild, important security patches may be released immediately.
