How to download and install the March 2014 security updates

Most Windows users will receive the updates via the automatic update feature of the Windows operating system. If you have not changed any update related settings, this is how you will get it as well.

Please note that you may need to check manually for updates to receive them as fast as possible, as Windows does not support real-time update checking.

If you have set your system to manual update, you need to either run the update check manually as well, or download the patches from Microsoft using the company's Download Center, or a third-party software that can do so for you.

Microsoft will release an ISO image in the coming hours that contains all security updates of the month. This too can be downloaded from the company's Download Center.

Consult our Windows Update guide to find out more about those options.
