Following the release of this month's Patch Tuesday updates, Microsoft has issued a warning that installing the KB5013943 update can lead to authentication issues for various Windows services.

The update was released on May 10, and was meant to -- among other things -- fix an issue with screen flicker in Safe Mode. But in addition to causing error messages for some users, the KB5013943 update has also led to authentication failures Windows domain controllers.

While each Patch Tuesday sees Microsoft fixing various problems with Windows 11, the following days see the negative fallout. We've become used to the updates that Microsoft releases having unwanted side, and this month's KB5013943 update is a prime example.

With echoes of a previous update fiasco that caused endless problems with printing, Microsoft intended the KB5013943 update to fix an issue with .NET Framework 3.5 apps introduced by another update. But rather than fixing the problem, installing the KB5013943 update seems to have made things worse for some users.

It’s Wednesday, so that usually (with occasional exceptions) means a new Windows 11 test build. Not today though, today Microsoft rolls out two new builds -- one for the Dev Channel (Build 25115) and one for the Beta Channel (Build 22621).

The Dev Channel flight comes with one new feature, but there is some bad news -- it won’t be offered to ARM64 PCs.

Windows users currently have a choice of two (supported) operating systems -- Windows 10 or Windows 11. While Microsoft would prefer users to be running the latest OS, adoption of Windows 11 has slowed dramatically in recent months.

When Windows XP first arrived back in 2001 it really shook things up with its revolutionary design and playful color scheme. If you were wondering how it might look if it was released today, we have the answer.

While the vast majority of people are happy downloading software these days, there are some who still gain comfort from owning physical installation media. Microsoft has listened and you can now buy Windows 11 and install it without the need to download anything -- or even needing an internet connection.

Microsoft has not exactly shouted about the availability of physical Windows 11 installation media, but it does exist. You can buy an official USB drive containing Windows 11 Home or Windows 11 Pro.

Wish and hope as much as you like, but the days of problematic updates for Windows are far from over. We now live in an age in which Microsoft releases patches for patches, and the latest example of this is the KB5013943 update for Windows 11.

This security update addresses a screen flicker problem experienced by some people who installed the KB5012643 update. It also fixes problems with .NET Framework apps caused by the same update.

In recent days the yet-to-be-released successor to Windows 11's Outlook app leaked online. Called One Outlook, this unreleased beta version is known as Project Monarch.

This is not the first we have heard of One Outlook; it was originally scheduled for release last year, but the launch was delayed. But the leak was the first time anyone has been able to try out the app, but Microsoft has issued a warning saying that this is an "unsupported early test version" which is missing features.

The new Microsoft Store web interface lists update dates once again for listed applications.

Today, Microsoft rolls out a new Windows 11 build to Insiders on the Dev and Beta Channels. This flight includes a few changes and fixes, including sorting a problem with the 'Show hidden icons' flyout in the system tray.

The big new addition in Build 22616 though is the new 'controller bar' aimed at Windows gamers with an Xbox controller.

It is not long since Microsoft released the KB5012643 update for Windows 11, bringing with it a lengthy list of improvements and security fixes. But, as has been the case with so many Windows updates, it also brought problems.

We have already seen issues with screen flicker in Safe Mode, although Microsoft has taken steps to address this. But now the company has issued a warning that Windows 11 users may experience issues with certain types of apps after installing the KB5012643 update.

After what seems like an age -- in reality just shy of four weeks -- it is time for a new version of PowerToys! Microsoft has released PowerToys v0.58.0, complete with a lengthy list of fixes and improvements to numerous utilities. Many of the changes will be of particular interest to Windows 11 users.

Under the hood, native ARM64 support is progressing, and NET Core 3.1 has been ditched in favor of .NET 6. More interestingly, there are also important change to FancyZones, File Explorer, PowerToys Runs, Mouse Utility and more.

When Microsoft released the KB5012643 update for Windows 11, there were complaints from a number of users about screen flicker when booting into Safe Mode.

Microsoft acknowledged the problem, and confirmed suspicions that it was related to Safe Mode with Networking. The company has now addressed the issue, fixing it with a relatively rare KIR (Known Issue Rollback).

There was no new build for Windows Insiders in the Dev Channel last week, and it looked as if we might not get one this week either, but at the death Microsoft releases a new build in time for the weekend.

Build 22610 introduces some new group policies for IT administrators, an update to the Family Safety Widget, and a large number of new fixes. However, it also introduces two known issues to be aware of.

Adoption of Windows 11 appears to have slowed down in the past two months according to recent usage statistics by third-parties.

Installing updates for Windows can often be something of a gamble, but this is particularly true when we're talking about the preview versions Microsoft makes available ahead of the monthly Patch Tuesday releases.

The latest problematic patch is the recently released KB5012643 update for Windows 11. Due for a wider release in May, Microsoft has already made a preview version available for those who like to get updated as soon as possible. But some people who have installed the update are reporting problems with flickering screens.
