The arrival of tabs in File Explorer would be an asset for Windows 11, but Microsoft seems reluctant to take action. Depending on the different builds for Windows Insider Program testers, the feature appears or disappears. Thus, it was present 15 days ago, in build 22572, then disappeared in build 22579, before reappearing in minor build 22579.100, and disappearing again in build 22581.

You should know that Microsoft uses several publication channels in its Windows Insider testing program. Thus, the Dev channel builds correspond to experiments that can be deployed in the more or less long term, or even abandoned along the way. In contrast, Beta channel builds correspond to specific Windows updates, for example the upcoming 22 H2 version of Windows 11 (codenamed Sun Valley 2). This is for example the case of build 22581.

If we follow Microsoft’s logic, the tabs could therefore not be present in the next major update of Windows 11. But that does not mean that the publisher is abandoning this function. It could appear in a point update, or within a cumulative update. Unless development problems push the deadline to versions 23 H1 or 23 H2 of the operating system.

Windows 11 Sun Valley 3, development will begin

Announcing Windows 11 build 22581 is a milestone. This is the kickoff of the development of the next evolution of the OS, Sun Valley 3

Windows 11 Sun Valley 3

PCs signed up to the DEV channel will soon transition to the CU (Copper) development branch. For our part, we are talking about Sun Valley 3 or even the third major version of Windows 11 scheduled for 2023. For its part, the beta channel will host the next versions of the NI development branch (Nickel). This is Sun Valley 2 or Windows 11 22H2 which is scheduled for release this year.

Note that the presence of the same version on both channels is the cause of a rather special situation. Knowing that it will not last if you want a more stable version of Windows 11 for the future you can migrate to the BETA channel. The operation is not complicated. It boils down to three steps.

Windows 11 Insider brings a new taskbar and more

According to a weekly ritual, becoming the first Windows 11 update available for both channels. This configuration will now be followed from now on. While the features released for the Dev Channel are not new, they are for the Beta Channel because it is not the first to receive new features that the Dev Channel usually receives.

Before moving on to the new changes in the latest build of Windows 11, here is an important update. Microsoft has revealed that it is now changing the way it releases builds for Dev and Beta channels and will now release the same build for both. While the former will test experimental features, the latter will preview features that can be considered closer to a release. However, not all features are intended to be launched.

The company also offers users the option to upgrade to the beta channel if they are part of the Dev channel. For this, users can head to Settings > Windows Update > Windows Insider Program > Choose your Insider Settings > Beta Channel Option, and voila. This option closes as soon as a higher build is published in the Dev channel. Microsoft should start releasing Windows 11 23H1 builds to the Dev channel soon.

The Windows 11 taskbar will clear itself as soon as a keyboard or mouse is disconnected and show important icons. Extended mode will make the taskbar more usable and also allow touch gestures. More taskbar improvements are being added with the new Insider Beta release.

Windows 10 / Windows 11: a critical 0-day flaw left unpatched by Microsoft

The vulnerability is of the “Windows User Profile service elevation of privilege” type and allows users to obtain administrator rights. This affects both Windows 10, Windows 11 and Windows Server.

Two security patches… that don’t work

The security flaw was discovered in the summer of 2021 by researcher Abdelhamid Naceri, who informed Microsoft about it. The Redmond firm deployed a first corrective patch in August 2021, but this failed to fully resolve the problem.

A new update was then made available in January 2022, but was also a failure, with Abdelhamid Naceri calling it an even less successful attempt than the first. Worse, with this second patch, Microsoft made inoperable an unofficial patch developed by the independent organization 0patch, which seemed to work correctly.

0patch had to publish in March a new patch compatible with the January update. For its part, Microsoft assures Bleeping Computer that “actions will be taken to guarantee the safety of users”. It remains to be seen when, this situation has already lasted seven months.

Microsoft is rolling out a new feature… to Windows 10

After 7 years of good and loyal service, Windows 10 is increasingly leaving its place in the spotlight to its replacement Windows 11… which does not prevent it (and fortunately) from continuing to benefit from regular updates. The latter nevertheless provide a minimum service, and are illustrated above all by security patches and a few minor additions.

The latest optional Windows 10 update nevertheless benefits from an interesting new feature: the addition of Search Highlights, items highlighted in searches operated from the taskbar.


Nothing fancy or groundbreaking with Search Highlights. These elements, however, complete quite well a research that Microsoft has greatly enriched on Windows 10 over time. For regular users, this little new feature allows you to display key events or information, such as holidays, birthdays or other important information at a regional or global level.

For professional users, this feature takes a slightly different form, this time highlighting key information linked, for example, to a Microsoft 365 account.

Note that the optional update KB5011543 also deploys some fixes to Windows 10. The bug that prevented users of Android devices from connecting to certain Microsoft applications, such as Microsoft Outlook or Microsoft Teams, for example, has been resolved. Same thing for the problem that made invisible the Back button, on the identification window, when the high contrast mode was active.
