Windows, Windows 10

It took Microsoft several days longer, but not as long as expected, to release the second cumulative update of September 2019 for Windows 10 version 1903.

The company published cumulative updates for other supported versions of Windows 10 earlier this week and the KB4517211 release for Windows 10 version 1903 completes the cycle.

The update is available on Windows Update and Windows Server Update Services, and also as a direct download on the Microsoft Update Catalog.

KB4517211 for Windows 10 version 1903

KB4517211 windows 10 1903 september 2019

KB4517211 is a non-security update that fixes issues for the most part. The update includes the following changes (which for the most part were fixed in Windows 10 version 1809 as well):

  • Fixed a vertical fonts printing issue when using PostScript printers.
  • Fixed a program starting issue that would return a "Access is denied" error when attempt to run 32-bit applications using "run as different user".
  • Fixed an USB write access issue when switching from a privileges to an unprivileged user.
  • Fixed an issue that caused lsass.exe to stop working.
  • Fixed the Windows Hello for Business issue that gave users two certificates for authentication instead of just one.
  • Fixed an issue that prevented web browsers from connecting to Windows Server securely.
  • Fixed an authentication issue for certificate-based authentication processes if a cname was part of the pre-authentication request.
  • Fixed an issue with Microsoft App-V applications failing to open and displaying a network error instead.
  • Fixed an issue with the Win32_LogonSession class which would display the value of the epoch instead of the actual logon time.
  • Fixed a File Explorer display issue that would show regular file icons for files with the offline attribute.
  • Fixed a VPN disconnection issue on cellular networks.
  • Fixed an issue that caused audio playback and recording to fail on remote virtual machine connections.
  • Fixed an issue in MSCTF.dll that would cause applications to stop working.
  • Fixed an input and display issue caused by imm32.dll.
  • Fixed a resizing issue in Windows Presentation Foundation applications that would not respond to the resize operation until the mouse button is released.
  • Fixed an issue that prevented older systems from upgrading to newer systems because "of an error in the display driver of older versions".
  • Fixed an issue on laptops with HDR screens that could cause the screen to turn white.
  • Fixed an issue when converting applications from 32-bit to 64-bit.
  • Addressed an issue that prevented users from running the Active Directory Diagnostics Data Collector Set from the Performance Monitor for Domain Controllers. This causes the Data Collector.
  • Fixed the audio issue in certain games that would made it quieter or different than expected.
  • Fixed an issue in Microsoft App-V that would prevent virtual processes from opening.
  • Fixed a power issue that would prevent maximum CPU performance from being available when selecting the High Performance plan.
  • Fixed an issue that caused devices to stop working when opening files from a network drive that has client-side caching enabled.
  • Introduces a way to configure the read buffer size.
    • This allows you to address an issue with slow upload times when uploading a file to a Universal Naming Convention (UNC) share using the Internet Information Services (IIS) Web Distributed Authoring and Versioning (WebDAV) feature.
  • Facilitates the configuration of devices that are managed by mobile device management (MDM) settings, which are created by ADMX ingestion.

Known Issues

Microsoft lists a single known issue on the support page:

  • Input Method Editors may become unresponsive or cause high CPU usage.

Workaround is available.

    Nice article!

    Since this is the first thing that popped up on Google when searching this update, I figure I should share my experience. I had the same issue as being described with my HP 8720.

    More concerning though, is that the update completely killed VMware Workstation which I use for all development and test servers. There is nothing like waking up in the morning to find a new Windows update installed and I cannot do my job.

    MS should rethink their update strategy. Why do we need these massive updates all the time? I have noticed 0 significant changes since the Win 10 release. I still use a Start button replacement (on my Host machine, not servers or development boxes) which is infinitely better than the Win 10 start interface. I personally would just like a stable/secure platform to run the programs I need to do my job. Stop making so many changes! If you want to make massive changes, put it all in one big update (ahhh… a service pack…) so I can setup a test system to check it out ahead of time.

    On my PC KB4517211 has turned the pen cursor in OneNote UWP into a very distracting mouse pointer when drawing on a graphic display tablet. Uninstalling KB4517211 restores the pen cursor to the dot it is supposed to be.

    don’t know why you are not covering these Martin:

    “Microsoft confirms printing bug in second September cumulative update for Win10 1903”

    “Windows: Printer issues after Sept. 2019 Update confirmed”

    I’m gonna reverse course and uninstall the KB4517211, KB4522016 & similar updates since the printing issues have been “confirmed” by MS

    – Would anybody be able to mention the Size of the KB…?
    Not mentioned on:
    … nor in WU while I’m on a Metered Connection…

    – Current KB is from 2019-09-26, 2 days after the OOB Patch for ‘CVE-2019-1367’ Zero-Day Memory Vulnerability in IE9/10/11 on ‘jscript.dll’, but I don’t see any mention about IE in this KB…
    => Not included, I guess…?
    => Is this current KB then a Requisite for the KB for IE…?

    1. Martin Brinkmann said on October 1, 2019 at 5:59 am

      The Microsoft Update Catalog website lists 311 Megabytes

      1. chivracq said on October 1, 2019 at 8:31 pm

        Oh…!, Thanks @Martin…!
        That’s a bit “too big” for my Metered Connection, ah-ah…!

        I managed to switch to an unmetered Co. yesterday but that Co. was very slow and unreliable, and the Download didn’t come any further than 13% for about 30Mb, so “your” 311Mb are indeed about the Size I was “expecting” then…, but the Download failed in the end… So OK, I’ll have to “try” some other way then…

        Thanks again…!

    hi Martin.

    Born is reporting that there are some printing issues caused by the KB4517211 update

  7. Larry said on September 30, 2019 at 12:56 pm

    I have attempted three times (July, August, & September) to install “1903” with no success as of this date. Every time the update stalled with the BSOD at the same % (90+) and every time I have had to shutdown my custom desktop PC. When I reboot I get an error message and I am back to my “1809” version of Windows 10 Pro.

  8. Adeel said on September 29, 2019 at 1:28 am

    I use AMD’s ReLive recording software to save video clips onto my hard drive and then I’m able to play them after each clip is saved.

    I’ve updated Windows to the latest version and now every time I playback a clip, the clip is extremely choppy and/or stuttery.

    I tried different video playback apps like VLC and I even tried watching the video through a browser, it’s still stuttering. This is happening for ALL videos, even old ones from months or years back. I also moved a clip from my hard drive to my SSD and the video is still choppy when playing back.

    Need help, thank you.

    Windows 10 Latest Version (September 28, 2019)

  9. Dirgster said on September 28, 2019 at 2:10 am

    I received the update, installed it on two computers, and had no problem doing so.

    1. Ozgen said on September 29, 2019 at 6:23 am

      Hi if you mean you are having sleep / awakening problems in your Lap top try to delete all Google related things including Chrome browser. I was about to get insane when a friend advise this and bingo , no more BSOD ( DPC WatchDog Violation) crashes (very much freq.) and no more awakening issues (8 to 10 sleeps). Pls. excuse me if I d’stract exact topic.

  10. George said on September 28, 2019 at 12:07 am

    Unlike the other W10 releases, there’s nothing here regarding sleep mode issues. Doh.

  11. GJ Weistra said on September 27, 2019 at 9:16 pm

    Thank you for the information, Martin. I just checked for updates, but didn’t get KB4517211, but KB4522738. The second last was KB4516115.
    Any idea why I didn’t get KB4517211? Maybe MS will unroll this later in Europe?

  12. Bobby Phoenix said on September 27, 2019 at 6:31 pm

    So I take it since it’s optional it will never get automatically installed? What if I have an issue that it fixes, but since I monitor several PCs, and all are set to automatically update, but I don’t check for these optional updates, the issue will never get fixed. I don’t think that’s smart on Microsoft’s part. If it fixes an issue, it should automatically install, and not just sit there forever waiting for user interaction.

    1. Martin Brinkmann said on September 27, 2019 at 6:38 pm

      It is automatically included in the next Patch Tuesday update.

      1. Bobby Phoenix said on September 27, 2019 at 7:46 pm

        Thank you for that info. I wouldn’t have thought of that.

    Another consecutive nail in the current W10 update coffin. I wonder the size of such coffin, considering people has been nailing since 2015. Please, Microsoft, turn back as soon as possible to the W7 update system with useful monthly updates and powerful Service Packs. Actually Windows 7 is more stable, useful and less problematic than W10 in every situation. I wrote here dozens of times that my father has W7 and all the family ask him to let his notebook sometimes, just because it works extremely good for everything, including old kind of hardware.

    1. Tom said on September 28, 2019 at 12:00 am

      yeah, w7 updates were not exactly what I would call “good”. They would hang indefinitely and peg the CPUs, randomly stop seeing new updates, require constant babysitting, and were a complete pain in the ass when patching a new OS install, which could take all day with the all the hanging, and resetting window update, rebooting, patching windows update, slow download speeds, and then the patches themselves which were enormousness and you had to run the updates many times to get them to all actually install.

      I’m not saying saying that W10 updates are great, but the W7 update system is not something that anyone should aspire to emulate.

      1. John G. said on September 29, 2019 at 7:12 am

        W10 size in disk and W10 updating mean times are by far uncredible bigger than W7 ones. Installing mean time of W7 is around 40 minutes, and restoring the whole disk is around 2 hours. Latest transition from W10 1803 to W10 1809 in my laptop needed more than 4 hours including two black screens and various unexpected reboots, unsuccessful and a complete waste of time. Then I decided to install it manually with ISO, spent on cleaning installation more than 6 hours, including 2 hours stuck at 75%. However it was successfully. Probably you are right about W7 updates, but obviously it’s easier to fix any kind of problem with W7.

        Win10 loves fast SSD’s and takes forever on hard drives, especially older 5400rpm ones. Get a Western Digital SSD — free cloning software is on their site (Acronis). Use a desktop machine as a mule to carry out the cloning process (boot second machine, then clone old hard drive E: to new SSD F: — the software allows for shrinking the old TB drive onto a smaller SSD if the HD’s used % is small enough, but the SSD likes being less than a third full so it can do “wear levelling” later). It has online help but it is confusing the first time…
        Win10 also loves big L2 cache — if you are running a Core2Duo, rip out that E4200 (2-MB L2) and stuff in a used Quad Core Q9550 (12-MB L2). Same socket, but it won’t feel like the same machine…
        If you do both SSD & CPU, bootup and updates will run 5x faster

    On successive WU tries I successfully got up to Microsoft Windows [Version 10.0.18362.387] with KB4515871, KB4517211, KB4520390, and KB2267602 installed with no problem so far.

  15. Paul(us) said on September 27, 2019 at 1:10 pm

    On (Today) 27 September at 13.01 hour I am getting the message from Windows after I have checked, with the Windows Update function, that there is no new cumulative update available.

    Could it be that Windows has pulled the update because of all the problems with this (longer tested because they wanted no problems) 1903 – KB45127211 update?

    1. Martin Brinkmann said on September 27, 2019 at 1:14 pm

      I don’t know to be perfectly honest. I got it just fine a moment ago on a test system. Maybe try to check again, it sometimes has issues.

  16. slothy said on September 27, 2019 at 11:07 am

    Fixed an issue since the last update that affected the wifi on my laptop. It would appear to connect and sync to the modem, but not acquire the correct IP.

  17. Bobo said on September 27, 2019 at 10:28 am

    Soooo, they didn’t release an updated .iso for 1903, that’s possible to install on machines since it has fixes that prevented installation. Instead you are supposed to install the old .iso, which you can’t, and then install this update. Yeah, that sounds just about right. Well done. Follows the same Microsoft philosophy where you are supposed to start your machine that doesn’t start in order to remove an update that made it not start. How would you describe Windows 10 and Microsoft in 2019? = Very horny, but very impotent.

      You can download the last ESD from, released this month. Windows 10 1903 18362.356.

    This is 3rd CU and search not working again. Ridiculous. Previous CU broke my start menu. Now menu start working but I can’t type anything. Last version which worked good was 18362.295

    1. Alex said on September 27, 2019 at 9:33 am

      Agree. Also on my PC notification center stopped working as well. The dread here is: so what now? Can’t ever update since these things are STILL not working? When will there be an update that won’t just repeat the same problems especially as they are “cumulative”.

    2. ard said on September 27, 2019 at 9:32 am

      @Anonumous, I still cannot understand that you are that quick with the upgrade. With your previous problems , you should know better

      Wait some days, a week and than after no negative info from fora like this comes, you may give it a try.

      Answer to Martin: No , I did no upload this upgrade, yet.

  19. windows10NotForever said on September 27, 2019 at 7:45 am

    This is not good. Outrageous. I’m used to scroll 3 to 4 times when viewing Windows issues.

    Unacceptable , this time i only had to scroll only once. Windows you’re letting me down.

    1. Martin Brinkmann said on September 27, 2019 at 7:57 am

      Yes that is refreshing. Then again, it usually takes a day or two before new issues are confirmed by the company.

      1. ilev said on September 27, 2019 at 8:24 am

        The update blocks .net 3.5 installation.
        The update breaks HP printers…
