Microsoft released security updates for all supported versions of its Windows operating system and other company products a moment ago. The updates are already available via Windows Updates and other update management systems.

Our overview is designed to help system administrators and home users make sense of the released updates. It acts as a one-page resource listing that links to relevant support articles on Microsoft's website.

It also summaries the published information. You learn about all confirmed issues, find out how specific client and server versions of Windows are affected, and get other handy information, including direct download links to the big patches.

We do include an Excel spreadsheet that you can download to get a list of the released security updates on top of that. In case you missed them, here is the link to last month's security updates overview.

How to download and install the September 2024 security updates

Security updates are installed automatically on non-managed Windows systems. On managed systems, it depends on the administrators configuration and system that is used to distribute the updates.

Updates are not installed in real time. Home users who want to protect their devices immediately may install the updates manually to speed things up.

This is done comfortably via Windows Update, or by downloading the updates manually from Microsoft's download site.

If you use Windows Updates, here is how it works:

  1. Select Start, type Windows Update and load the Windows Update item that is displayed.
  2. Select check for updates to run a manual check for updates.

Note: Make sure you have a recovery plan in place, e.g., by creating a system backup before you install the update. Windows update can and have failed in the past.

Direct update downloads

Below are resource pages with direct download links, if you prefer to download the updates to install them manually.

    As usual stuck at either 20 or 70% downloading then it starts again, Although this time it was faster as usual.

    Oh and disabling my Realtek PCIe Adapter. My – after the updates- attached external hard drives were vanished. The troubleshooter pointed it out.

    Kind of Windows roulette. You never know if one day it will be a direct hit. Gonna reading a book now.

    Note: This is off topic. I always wait a few weeks for you guys to find all the bugs before I install OS updates.
