How to download and install the April 2014 security updates

The updates are as usual available via Windows Update. This is usually the way they are deployed on most home systems as Windows Update is configured to automatically download and install security updates.

The updates are available already. You may want to check for updates manually as it may take a while before Windows checks for updates again.

To do so, press the Windows-key and enter "windows updates" and select that option to run a manual update check.

You can download all updates from Microsoft's Download Center as well. The company will release a security ISO containing this month's patches as well which you can download. It takes some time before it gets released though.
