Windows Vista, 7, and 8 are updated via the Windows Update interface. It is usually okay to let it install recommended updates, but there may be unforeseen compatibility issues with other software on your system. For example, some businesses run software that is not compatible with the latest versions of Internet Explorer.
Because Microsoft frequently releases minor security patches through Windows Update, it is usually best to install recommended updates. Not updating may put your computer at risk.
Always keep your computer plugged into power while it is downloading and installing updates. Windows system files can easily become corrupted if updates are interrupted.
