How to download and install the December 2022 security updates

Most Home systems are updated automatically thanks to the built-in Windows Update feature. The checks for updates do not happen in real-time, and some administrators may want to download them as soon as they are released to their devices.

This is done using a manual update check. Do the following to run a manual check for updates:

  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.

    One entire month waiting to resolve >60 vulnerabilities in W10/11, absolutely nonsense method of updating these OS, mainly because the critical ones should be updated weekly or even daily due to the high security risks that may cause to all the affected Microsoft’s users. Currently the people are connected almost all day and in one hour of critical bugs or vulnerabilities they can be hacked and get into several problem! Thanks by the way for the good summary and for the article. :]

      Alright.
      You develop updates of the most used operating system on the planet, ran on an almost infinite combination of hardware parts.

      @John G.

      What you suggest would lead to chaos as there would be a constant scramble to install updates and subsequent troubleshooting as updates break things. That is why a long time ago Microsoft (and many other major software makers) moved to a once a month schedule in order to provide a more predictable and stable roll out of updates which is especially important for businesses/corporations that require high availability/functionality of their systems (servers and desktops).

      Also updates alone do not determine the security of a system and whether or not it can be compromised. There are other more important layers of security that help protect a system, one of the biggest and easiest to implement is a firewall that blocks all incoming connections as the vast majority of vulnerabilities require remote access to the system in order to exploit. So no reason to panic and operate with the mindset that you must install the latest updates immediately in order to be protected. That only gives you a false sense of security.

      I just meant that it’s not good to wait one entire month to receive more than 60 fixes for critical bugs in W10 and in W11. Such an amount of bugs!

    Well that is it. The very last monthly update for Windows 7 has come…

    It’s been much easier updating windows 7 with your monthly overview Martin. Thanks much for your great help, every month, every time for all those years.

    I will soon transfer my activities to a new MacOS platform and most probably won’t experience windows again.

    I won’t complain…

    Cheers!

      pause

      Then restart the computer and please try again to update.
      If this fails, then be caution of third party software like O&O or others than can modify the update system of the Windows (e.g., I had in the past several problems with Explorer Patcher).
      If everything fails, just wait a month and then try a hard update on the fly with the latest ISO file of Windows, using the media creation tool (you can find more info at the internet, it’s easy to do).

    You’ve got to love all of the:

    “Remote Code Execution Vulnerability” fixes…

    How embarrassing, yet nobody seems to care!

    With every version of M$’s chewtoy, come tons of these “Remote” holes. I wonder why.

    Enjoy whatever “protection” you think you have from your black box Operating System.

    Reminiscing as I find it nearly impossible to find meaningful information on the site: senseless dribble.

    {Not the current article; I find the links useful–and the comments. Thanks!}

    And what to celebrate today? RIP gHacks t-shirts should go on sale.

    @Paul(us) Glad you found an upgrade worth the time; in one of your last comments, I thought you had jumped ship. I still find Windows 10 to be a worthy OS; Windows 11 takes some work with tweaks, but stability is there.

    In your executive report you mentioned – “The following client versions of Windows have known issues: Windows 7, Windows 8.1, Windows 10 version 1809, Windows 11 version 22H2”

    What known issues do we have in Win 10 ver 1809?
