Microsoft just pushed out a new build of its upcoming operating system Windows 10 to Fast Ring users of the Windows Insider program which upgrades it to build 10158 in the process.

The new version introduces a series of changes to the operating system over build 10130

Attention: You need to backup Favorites manually while still on build 10130 due to a change in app ID as Microsoft finally rebranded Project Spartan to Microsoft Edge, the final name of the new web browser of Windows 10.

Microsoft notes that favorites, cookies, the browsing history and reading list will be lost after the upgrade.

To backup the favorites, copy them from the folder %localappdata%/Packages/Microsoft.Windows.Spartan_cw5n1h2txyewy/AC/Spartan/User/Default/Favorites to the %userprofile%/Favorites folder of the system.

Then you need to select Settings > Import Favorites after the upgrade in the new Microsoft Edge browser to import the backed up favorites again by selecting Internet Explorer.

Microsoft made several changes to the browser. Some introduce core browser features that Microsoft Edge was missing up until now including drag tabs to a new window, password and form-fill support, and data import from other browsers.

Others introduce features to the browser which you need to enable before they become available. To enable the dark theme for instance, you have to click on the three dots in the main toolbar, select settings when it opens and there the dark theme.

You may also add a dedicated Home button to Edge under advanced settings or change what is displayed when you open a new tab page in the browser or start it.

You are probably wondering how Edge is performing, especially in comparison to other browsers. It came out on top in a quick benchmark test against the most recent stable versions of Firefox and Chrome beating both browsers by about 2000 points.

While Microsoft Edge is performing well and may be attractive because of that and because of how stripped down it is, its lack of features makes it less attractive to users who like to customize the browser.

Extension support is not available yet and it remains to be seen how Microsoft will implement it after all.

The new Windows 10 build ships with a bunch of improvements that will mostly appeal and be noticed by mobile users.

Cortana got updated for instance with a new dark theme and lots of improvements. You may now track flights using it for instance or let it write entire emails for you (only U.S. English supported right now). You may also notice UX improvements and if your company is opted into First Release for Office 365, may test the integration of Cortana with Office 365.

Mobile users may swipe to the left when the start menu is open to display all applications. In addition, it is now possible to click on the letters in the all apps listing to jump quickly to one which should benefit users with lots of applications installed. It is unfortunately not possible to tap on a key on the keyboard to jump to the letter or character.

Microsoft released an updated Photos application exclusively for Windows which supports animated gifs now.

The classic Windows Store seems broken in the release which means that you are left with the new store instead which gives you less control and options.

It is for instance no longer possible to sort apps in categories, for instance by newest, which you could do in the classic store. This means that it is no longer possible to explore categories in the store to find out what is new.

Microsoft appears to have copied Google's user-unfriendly store design in this regard as Google Play does not provide you with these options either.

The company improved the Snipping Tool in the newest build. While it is still rather basic when compared to dedicated screenshot programs, it is now supporting delays which can be useful if you want to capture menus for instance. The only option you had previously to capture menus was to use the Ctrl-Print shortcut to invoke it directly without clicking on its capture button.

Microsoft plans to release a preview of the Windows 10 SDK later today.

Now You: Have you tried the new build yet? What's your take on it?

    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.
