Windows, Windows Updates

Microsoft has just pushed out up to three new patches for the retail version of its Windows 10 operating system.

Windows 10 users who have not modified Windows Update settings may notice them when they run a manual check for updates.

The patches in question are the following ones:

  • Cumulative Update for Windows 10 for x64-based Systems (KB3081448)
  • Update for Windows 10 for x64-based Systems (KB3081449)
  • KB3081452 (this one did not land on test systems I run)

It is likely however that these patches get installed on most systems automatically. What makes this problematic is that Microsoft has yet to publish the corresponding Knowledge Base support pages on the official website.

windows updates kb3081448 3081449

No information except for basic patch titles such as "cumulative update for Windows 10" or "update for windows 10" are provided when you check for updates.

Update: The support pages are available now but they don't reveal (many) additional information about the updates Microsoft released yesterday.

  • KB3081448 Cumulative Update for Windows 10: August 27, 2015 - This update includes improvements to enhance the functionality of Windows 10.
  • KB3081449 OOBE Update for Windows 10: August 27, 2015 - This update improves the Windows 10 out-of-box experience (OOBE). This update applies only to the Windows 10 OOBE process and will be available only at the time that OOBE updates are installed.
  • KB3081452 August 27, 2015, compatibility update for upgrading to Windows 10 - This update makes improvements to ease the upgrade experience to Windows 10.

Why is that an issue?

While the majority of users may not care about patch notes or what patches actually do or change on the system, some users prefer to know what gets installed on their computer systems.

These users have good reason for that too considering that past Windows updates did wreak havoc on some systems.

Apart from bugs that may cause issues on Windows 10 systems, it is privacy and security that plays an important role.

Some users may not want updates to install new telemetry features on the system for instance, or change privacy settings or add new ones.

It is impossible to qualify updates that are released if information about them are not released at all or not in time.

Microsoft released a tool recently that Windows 10 users and administrators can use to block updates that they have installed already. It is difficult to block updates from being installed in first place though as Microsoft modified the automatic update behavior of the Windows 10 operating system.

Windows 10 Home systems are affected by this especially as they cannot defer the installation of updates. This privilege is reserved to Windows 10 Pro and Enterprise systems.

Probably the best course of action right now is to wait until the patch notes are released by Microsoft. While this may reveal information about those patches, there is no guarantee anymore that this is the case as Microsoft made it clear recently that it may not release full patch notes for select Windows Updates anymore.

We will update the article when official information about these three patches are released by Microsoft.

In related news, Microsoft published a new Windows Insider build today. Build 10532 for PC improves the consistency of context menus, and better sharing options for feedback.

    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.

      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.

    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.
