To open the Update interface, first click the Start menu button in the lower-left corner of Windows. In the search box, type Update. Click on Windows Update from the list that appears.
In the left pane, click on Check for Updates. Windows determines whether updates are available. You may have to wait, as it can take a few minutes for all of the updates to populate.
If updates are available, they appear in a list. Some of the updates may be marked as important. Review the updates to decide which updates you want to install, as you may only want to only install the important updates. Click the check box next to the updates you want to install.
Once you have selected the updates you wish to install, click Install Updates. Read and agree to the licensing terms before clicking Finish. Depending on your system settings, you may need to enter your administrator password. The updates are installed.
