How to download and install the May 2015 security updates

microsoft security-bulletins updates may 2015

Updates are already available via Windows Update. Since update checks are not run in real-time, you may want to run a manual check for updates to find and install the updates as soon as possible on your system.

To do that, tap on the Windows-key, type Windows Update, hit the enter-key and click on check for updates in the window that opens.

Cautious users may want to wait with the installation as updates may have unforeseen consequences on systems as the past has shown.

Updates can be downloaded individually from Microsoft's Download Center or via monthly released security images.

You may also find third-party tools like WSUS helpful in this regard.
