Windows, Windows 10

It always takes a bit longer before the second cumulative update of a month is published by Microsoft for the current version of Windows 10.

The company changed the update testing and release strategy some time ago after the Windows 10 version 1809 release fiasco to test updates in the release preview ring before they are made available to all devices running the version of Windows.

Microsoft released the cumulative updates KB4501371 and KB4503288 for Windows 10 versions 1809 and 1803 on June 19, 2019, and the updates KB4503277 and KB4503283 for Windows 7 and 8.1 on June 21, 2019.

Note: KB4501375 is considered a preview update, not a final update. It should not be installed on production machines but is suitable for testing purposes. In any case, make sure you create backups before you install the new version.

The new cumulative update shares many of the fixes of KB4501371 and KB4503288 that Microsoft released earlier this month.

Here is what is fixed and improved in the new update:

  • Fixed a cursor display issue when moving the cursor over the keyboard magnifier.
  • Fixed a redirects issue in Edge and Internet Explorer 11.
  • Fixed an issue with Scalable Vector Graphics marker display.
  • Fixed a programmatic scrolling issue in Internet Explorer 11.
  • Fixed a display issue in Internet Explorer caused "under certain conditions" on sites with "many elements and multiple nesting levels".
  • Fixed Error 1309 when installing or uninstalling certain msi or msp files on a virtual drive.
  • Addressed an issue that caused Night Light, Color Management profiles, or gamma correct to stop working after shutdowns.
  • Fixed an issue that showed grayscale only during Windows Hello enrollment.
  • Fixed an issue that caused playback of iOS media to fail under certain circumstances.
  • Fixed a taskbar and desktop flickering issue in Windows Server 2019 Terminal Server.
  • Fixed a policy issue that allowed users to set backgrounds even though a policy to prevent that was set.
  • Fixed a connection issue when using fitness software on Android devices with Your Phone installed.
  • Fixed a Windows Event Log issue that prevented the service from processing notifications that the log is full.
  • Fixed an Office 365 opening issue when deployed as App-V packages.
  • Fixed an issue that prevented Container Hosts from receiving addresses from DHCP servers.
  • Addressed an issue that prevented Windows 7 to 10 installations from completing when certain antivirus applications were installed on the system.
  • Reinforces the Certificate Revocation List on Internet Key Exchange version 2 machines for certificate-based virtual private network connections.
  • Fixed an issue that triggered Group Policy updates even though there were no changes.
  • Fixed the Preboot Execution Environment startup issue.
  • Fixed the Custom Views issue in the Event Viewer.
  • Fixed a WinHTTP registrations issue that delayed the startup of the operating system. The issue occurs on devices with proxy auto-config files. Microsoft notes that admins need to make the following changes to the Windows Registry to stop the incremental growth of the Registry:
    • Path: HKEY_CURRENTUSER\"Software\Classes\Localettings\Software\Microsoft\Windows\CurrentVersion\AppContainer\Mappings"
    • Setting: CleanupLeakedContainerRegistrations
    • Type: DWORD
    • Value: 1 (1 removes preexisting registrations, 0 retains them)

Microsoft lists just one known issue for KB4501375. The sandbox issue is still a thing in the new version..

Now You: When do you install the secondary updates of the month?

    What mental age of reader are you targeting with the first sentence? 10?

    Why not write an article on how to *avoid* upgrading from W10 to W11. Analogous to those like me who avoided upgrading from 7 to 10 for as long as possible.

    If your paymaster Microsoft permits it, of course.

    5. Rufus
    6. Ventoy

    PS. I hate reading these “SEO optimized” articles.

    1. cdr said on January 15, 2023 at 3:32 pm

      I used Rufus to create an installer for a 6th gen intel i5 that had MBR. It upgraded using Setup. No issues except for Win 11 always prompting me to replace my local account. Still using Win 10 Pro on all my other PCs to avoid the bullying.

    bit pointless to upgrade for the sake of upgrading as you never know when you’ll get locked out because ms might suddenly not provide updates to unsupported systems.

    ps…. time travelling?

    Anyone willing to downgrade to this awful OS must like inflicting themselves with harm.

  5. basingstoke said on January 16, 2023 at 11:18 am

    I have become convinced now that anybody who has no qualms with using Windows 11/10 must fit into one of the following brackets:

    1) Too young to remember a time before W10 and W11 (doesn’t know better)

    2) Wants to play the latest games on their PC above anything else (or deeply needs some software which already dropped W7 support)

    3) Doesn’t know too much about how computers work, worried that they’d be absolutely lost and in trouble without the “”latest security””

    4) Microsoft apologist that tries to justify that the latest “features” and “changes” are actually a good thing, that improve Windows

    5) Uses their computer to do a bare minimum of like 3 different things, browse web, check emails, etc, so really doesn’t fuss

    Obviously that doesn’t cover everyone, there’s also the category that:

    6) Actually liked W7 more than 10, and held out as long as possible before switching, begrudgingly uses 10 now

    Have I missed any group off this list?

    1. Heinz Strunk said on September 19, 2023 at 3:57 pm

      You have missed in this group just about any professional user that uses business software like CAD programs or ERP Programs which are 99% of all professional users from this list.

      Linux doesn’t help anyone who is not a linux kid and apple is just a fancy facebook machine.

    Microsoft has removed KB5029351 update

    1. EP said on August 24, 2023 at 9:21 pm

      only from windows update though
      KB5029351 is still available from the ms update catalog site

  7. Anonymous said on August 24, 2023 at 11:05 pm

    1. This update is labaled as PREVIEW if it causes issues to unintelligent people, then they shouldn’t have allowed Preview updates ot install.

    2. I have installed it in a 11 years old computer, and no problems at all.

    3. Making a big drama over a bluescreen for an updated labeled as preview is ridiculous.

    This is probably another BS internet drama where people ran programs and scripts that modified the registry until they broke Windows, just for removing stuff that they weren’t even using just for the sake of it.
    Maybe people should stop playing geeks and actually either use Windows 10 or Windows 11, but don’t try to modify things just for the sake of it.

    Sometimes removing or stopping things (like defender is a perfect example) only need intelligence, not scripts or 3rd party programs that might mess with windows.

  8. john said on August 24, 2023 at 11:17 pm

    Windows 11 was a pointless release, it was just created because some of the Windows team wanted to boost sales with some sort of new and improved Windows 10. Instead, Microsoft cannot support one version well let alone two.

    1. John G. said on August 25, 2023 at 12:08 pm

      Windows 11 is the worst ugly shame by Microsoft ever. They should release with every new W11 version a complete free version of Starallback inside just to make this sh** OS functionally again.

    While there may be changes or updates to the Windows 10 Store for Business and Education in the future, it is premature to conclude that it will be discontinued based solely on rumors.

  12. sembrador said on September 5, 2023 at 9:32 pm

    My advice, I left win 15 years ago. Now I’m a happy linux user (linuxmint) but there is Centos, Fedora, Ubuntu depending on your needs.
