How to download and install the February 2020 security updates

microsoft windows security updates february 2020

The security updates that Microsoft released on February 11, 2020 are made available via Windows Update, WSUS, and other updating tools and services. The updates may also be downloaded manually and installed just like any other application on Windows machines (check the section below for direct download links).

Note: Since Windows updates may introduce bugs or issues, it is highly recommended to create backups of important data -- better the entire system -- before running any updates.

To check for updates manually, do the following:

  1. Open the Start Menu of the Windows operating system, type Windows Update and select the result.
  2. Select check for updates in the application that opens. Updates may be installed automatically when they are found or offered by Windows; this depends on the operating system and version that is used, and update settings.

    I got KB4524244 on my Win 10 Pro 1909 and my 3 Win 10 Home 1909 machines. According to link it should ONLY be for Win 10 versions 1903 and below.

    On all my machines it was offered after manually checking for updates, after the other 3 Feb updates had been successfully installed and the machines had been restarted.

    Should this be uninstalled?

    As is usual, Windows Update knew enough to install SSU KB4538674 to get me updated to Microsoft Windows [Version 10.0.18363.657]. Only way I knew that was to later run Belarc Advisor on my home laptop, and then see

    Acer Aspire V5 571G, Windows 10 1909 x64 installed 4 days ago on a spanking new Intel SSD. All drivers updated. No programs installed. All good until yesterday, cumulative update KB4532693 fails repeatedly with error 0x80070003. Tried EVERY solution found online, then restarted and tried again. This has now failed 9 times in a row, there will not be a 10th time because this thing goes back in the closet to wait for Kubuntu 20.04. ..I had this crazy thought that my mom would probably use this laptop more with Windows on it, I should have known better..I think she’ll actually live longer and healthier with anything else than Windows on it. Windows 10 is for masochists. It never ceases to amaze me, year after year after year, what a miserable piece of a rotten turd Windows 10 is. Since there’s a little sadistical masochist bizarro-perv in me, I will give this a go again in a year or two I’m sure.. just to get hammered good again, and come here to bitch about it.

      @Bobo,

      Corrupt system file somewhere usually causes that error.
      Run: DISM.exe/Online /Cleanup-image /Restorehealth from an elevated command prompt and then try installing again.

      Also, do you have all the Servicing Stack updates installed?

        Trust me, everything is done and every update and driver is in place. The culprit is the cumulative f**kupdate, as is tradition by now. I don’t care anymore, won’t waste another second in Windows 10 nightmare-world with that computer. A 2012 model, not THAT old IMO, 500GB SSD, 8GB RAM, AC-WIFI, BLUETOOTH, the works.. all good, except it comes with a freshly installed, broken unusable SUPERPOTATO-OS =) Sweet Lord baby Jesus how EXCREMENTY Windows 10 is, cumulative defecation every month free for aaaaaall.

      If it’s the portable version, you can rename the .exe files to something like cc.exe and cc64.exe and run it.
      You can also disable Program Compatibility Assistant through Services and GPEdit: https://i.imgur.com/UdhFjSQ.png
      Too lazy to type the whole path so here’s a screenshot. I always disable PCA ever since Vista, it’s useless and annoying.

    For me, their feature updates install smoothly and quickly, but their cumulative updates and the menagerie of all the huge ‘cumulative’ updates and stupid little definition updates et al, should be called Chaos Tuesday. Took 2 days of rigamarole to finally get their little butts into Windows and everything calm again.
    Ah for the days on Vista when I disabled Updates for a year and a half…and really didn’t see much of an effect from it…at least nothing that I couldn’t fix myself (and I’m no techie).

    KB4532692 shows as a “critical” dynamic update on MS Update Catalog, yet it’s listed here as a “non-security related update” and the link for it say “Compatiblity Update…”. Another MS update snafu, guess I’ll just ignore this one, wouldn’t install anyway and there’s no doc on it for install.

    I used WU to correctly update on 2/11 to Microsoft Windows [Version 10.0.18363.657]. On 2/14 I used WU again, which installed KB4524244 without a restart, so I did one and see no problems for me. Documentation I know of did not tell me KB4524244 should have been installed.

    I’m still on Windows 7 and the updates downloaded automatically onto my PC. I’m not on extended support so, having read scare stories, I haven’t done a shut down which will cause an automatic install of these updates. Has anyone else had this?
