Look up deleted Microsoft KB articles

Microsoft started to use its Docs website in 2016 to publish new articles. The company retired the classic MDSN and Technet sites and migrated these to an archive on the Docs site as well.

The company started to clean up its support pages in 2018 by deleting articles on these sites. It is unclear how many articles were deleted by Microsoft but users from all over the world started to get 404 errors in their browsers when they tried to access these support articles.

One option that users have in that case is to use the Wayback Machine that is maintained by the Internet Archive. Just paste the URL of the support article to see if an archived copy is available.

microsoft kb archive search

The Microsoft KB Archive Search is a new solution that makes things a bit easier. It was launched on January 29, 2020 to the public.

The company that maintains it provides insight on why it created the solution:

It all started when we started to notice Microsoft was archiving/deleting Support KB articles from it’s site – often even when the information was still pertinent. We started noticing a number of the items we track in the ADCS Hotfix Digest were soft-failing when hitting the Microsoft site (no 404 error). So we weren’t even being notified by our own tools about the deletion.

When we reached out to the Microsoft product team for ADCS they weren’t even aware the articles were being archived as it wasn’t at their behest. After several weeks it became clear the articles weren’t coming back and the problem would continue to affect us all.

It provides a searchable interface that accepts KB IDs, titles, or parts of the description. The project lets users search across more than 49,000 articles of which 788 are no longer available on Microsoft's own site.

All available results are displayed once you hit the "search in offline" button. Each item is listed with its full title, KB ID, and a short description.

A click opens the details page which provides the same information that Microsoft provided when it published the article (or updated it for the last time).

Note that you may see links that point to resources that are no longer available; you may get Technet or MSDN links that are not redirected by Microsoft. One option that you have in that case is to try to find a copy using the Wayback Machine.

microsoft kb browse

Microsoft KB Archive Search provides a second option besides search. A click on "browse products" displays a long list of Microsoft products and the article count for each.

If you are looking for support articles for a particular product, e.g. .Net Framework 3.5.1, Application Server, or  Exchange Online, you may use it to find all matching articles faster. One downside is that the listing is divided into 30 pages that you need to browse one-by-one. There is no option to jump to a specific character or letter, or search for a particular product.

Tip: you can change the number in the URL to quickly jump to a page.

Closing Words

Microsoft KB Archive Search is a handy solution for administrators and users who need to access support articles that Microsoft deleted. While the Wayback Machine may work as well for individual articles, the built-in search and product browser allows you to retrieve all articles matching a particular product or service.

    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.

  3. sv said on January 15, 2023 at 6:40 pm

    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?

      This happens when you schedule a post in WordPress and update it before setting the publication date.

    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.

    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.

    motherboard maker MSI has recently released a statement regarding the “unsupported processor” blue screen error for their boards using Intel 600/700 series chipsets & to avoid the KB5029351 Win11 update:

    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.

  13. EP said on September 6, 2023 at 11:55 am

    motherboard maker MSI has recently released new BIOS/firmware updates for their Intel 600 & 700 series motherboards to fix the “UNSUPPORTED_PROCESSOR” problem (Sept. 6):
