Using the Windows Update tool

Open Windows Update using the steps mentioned above. You will see a set of updates that are currently available. The updates are customized according to your device. Choose those updates that you wish to install. Follow through the next set of prompts. The whole process is generally fully automated with few actions from the user. After the updates are downloaded and installed, you may have to restart your device.

Windows update is different from Microsoft Store. The Store is for downloading applications and music. Windows update can be used to update device drivers too. But users prefer to update the device drivers (video card driver, the driver for a keyboard, etc..) by themselves. The free driver updater tool is a popular tool used to update device drivers.

The previous versions before Windows update

When Windows 98 was in use, Microsoft released the critical update notification tool/utility. This would run in the background. When a critical update was available, the user would get notified. The tool would conduct a check every 5 minutes and also when the internet explorer was opened. Through this tool, users received regular notifications about updates to be installed.

In Windows ME and 2003 SP3, this was replaced with Automatic updates. The automatic update allowed installation without going to the web browser. It checked for updates less frequently compared to the previous tool (once every day to be precise).

With Windows Vista came the Windows update agent which was found in the control panel. Important and recommended updates would automatically be downloaded and installed by the Windows update agent. Until the previous version, the system would restart right after a new update was installed. With windows update agent, a user could reschedule the mandatory restart that completes the update process to a different time (within four hours of the installation).
