Windows Update

Microsoft has managed to do it yet again. On the face of things, the KB5070311 preview update is a great update that not only addresses problems such as File Explorer freezing, but also introduces a raft of new Copilot features.

But, as you will have probably gathered, it does not end there. The KB5070311 preview update is another issue-riddled update, this time breaking dark mode in File Explorer.

It is far from uncommon for Microsoft to release an update for Windows that causes problems with the operating system itself. It is also not unknown for Windows updates to cause issues in other software – and this is what some gamers have experienced.

In releasing a new GeForce Hotfix Display Driver, NVIDIA has pointed the finger of blame at a recent update for Windows 11 for slowing down the performance of some titles. Despite NVIDIA’s claims, Microsoft is yet to say anything about the issue.

If you have suddenly found it more difficult to log into Windows 11, you should know that you are not alone. Microsoft has just confirmed that a recent update had the unwanted side effect of hiding the password sign-in option from the lock screen.

This was not something that all users of Windows 11 will have been affected by as there are various factors to consider. Nonetheless, this is a worrying problem that has caused a good deal of confusion and is still yet to be resolved.

Microsoft has acknowledged a serious issue with Windows 11 24H2 which it says can cause “multiple symptoms”. The problem has been around for a number of months now, and occurs when provisioning systems with cumulative updates released from July 2025.

The list of potential issues caused by the bug includes problems with File Explorer, the Setting apps, the Start menu, the Taskbar and more besides. While it is good that Microsoft has now confirmed that it is aware of the issues that have been affecting people for so long, the company is yet to come up with a proper fix – only a workaround.

The end has been nigh for Windows 10 for what feels like an eternity, but Microsoft finally pulled the plug on mainstream support last month. After a confused period of communication and a few niggles, the company has now released the first Extended Security Update for the operating system.

With the release of the KB5068781 update, Microsoft is now only addressing problems with Windows 10. With the ESU program now in operation, no new features should be expected.

Microsoft has made another admission that its updates for Windows may have caused problems for some people. The company says that updates released for Windows 11, version 24H2, Windows 11, version 25H2, and Windows Server 2025 in August and September could have resulted in login issues for some.

There are two offending update – namely the August 29, 2025—KB5064081 (OS Build 26100.5074) Preview and September 9, 2025—KB5065426 (OS Build 26100.6584) – which Microsoft says could lead to Kerberos and New Technology LAN Manager (NTLM) authentication failures.

Microsoft has been forced to release an unscheduled update for Windows 11. The newly unleashed KB5068221 update addresses issues with Microsoft Office running in virtualized environments.

For those who have been experiencing the issue, the fact that this update fixes things is reason enough to install it. But Microsoft has also used this update release to share details of a workaround for a SMBv1 share problem.

Microsoft has admitted that the security updates released for Windows in August caused problems for a lot of users. Affected users experienced a series of unexpected UAC (User Account Control) prompts.

The scale of the issue is large. This is not a problem that is limited to a particular version of Windows – every supported version of Windows that received the August 2025 security update is affected. This means that Windows 10, Windows 11, Windows Server 2022 and Windows Server 2025 have all been hit with the UAC prompts.

Microsoft has released the KB5062660 preview update for Windows 11 ahead of next month’s Patch Tuesday. Being a preview update, it is optional and does not include security fixes, but it is packed with new features including the Windows Resiliency Initiative.

This initiative is something Microsoft spoke about back at Ignite 2024 and it aims to boost security and reliability. The update delivers two components of this. It sees the arrival of Quick machine recovery as well as the new Black Screen of Death.

Following complaints from users about problems with Windows Server Update Services, Microsoft has spoken out. The company has confirmed that WSUS has suffered issues preventing synchronization and deployment of updates.

This is a serious headache for businesses and organizations that rely on WSUS to manage Windows updates across networks. Reports of errors have been popping up for a couple of days, with scheduled synchronization actions showing to have failed in event logs.

Microsoft has released the KB5062553 update for Windows 11 24H2. Billed primarily as a security update for the operating system, it is actually more than that – much more.

As is the case with Microsoft’s monthly security updates, it also includes the non-security improvements, fixes and additions that were previewed last month. One of the key new arrivals here is the new PC-to-PC migration experience which uses the Windows Backup app to ease the process of moving to a new computer.

Microsoft has issued a warning about a recent update for Windows 11. The KB5060829 update was released late last month as a non-security preview update, and it has been found to be causing issues.

Available for Windows 11 24H2, the optional KB5060829 update has been causing Windows Firewall With Advanced Security errors to be logged by the operating system. While error message relating to a security feature are likely to result in concern and fear, Microsoft is at pains to reassure users that there is no need to panic.

Following the release of the KB5058405 update last month, Microsoft acknowledged that it was causing problems for some users. Affected users were left with startup issues and a warning of a 0xc0000098 error in the ACPI.sys file.

Now the company has released an out-of-band fix for the issue in the form of the KB5062170 update. Such is the impact of the original problem that Microsoft recommends installing this update in place of the May 2025 security update for Windows 11.

Windows updates that cause problems are far from being uncommon, sadly, but the latest issue is a pretty serious one. Some users who have installed the KB5058405 update from earlier this month have found themselves with an non-booting system.

Those affected will note a 0xc0000098 error in the ACPI.sys file, and a message informing them that their device needs to be repaired. The bad news does not end there. Microsoft does not yet have a fix -- or even a workaround.

Microsoft has released a preview version of the KB5058499 update for Windows 11, adding a host of new features to the operating system -- many of them, predictably, AI-oriented.

The biggest additions are updates to Click To Do, as well as the rollout of the new Windows Share feature. There is also “Cross device resume” to allow for seamless device migration when using OneDrive files, and much more.
