On Windows 7 and previous versions of Windows, Windows will start to nag you after installing most updates.
It will pop up and inform you that it’s restarting your computer in fifteen minutes unless you postpone the shutdown.
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.
While Windows Update can be obnoxious, it keeps your computer secure and is well worth using.
It can also be made less obnoxious with a few quick settings changes.
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.
