When Microsoft released the KB5062553 update for Windows earlier this month, it addressed a number of issues in the operating system. However, it also caused problems with Azure Virtual Machines.

As such, Microsoft has been forced to publish another emergency patch to fix a problem caused by one of its own software updates. This time around, the out-of-band fix is the KB5064489 update, and it is available for both Windows 11 and Windows Server 2025.

VMware’s Fusion and Workstation products have been go-to solutions for millions, allowing users to create local virtual environments on Windows, Linux, and Mac computers. These tools are essential for installing other operating systems, learning about technology, and developing and testing software. Now, there’s exciting news for the VMware community.

As VMware integrates Fusion and Workstation into Broadcom, they are making a HUGE change: Fusion Pro and Workstation Pro are now free for personal use. Yes, you read that right – free! This is a game-changer for tech enthusiasts and developers who want to run virtual machines on their personal devices without breaking the bank.

Microsoft has updated the free virtual machines it makes available for download as Windows 11 development environments.

In addition to Windows 11, the virtual machines also include various other developer-centric tools such as Visual Studio 2022 Community Edition and Ubuntu pre-installed in Windows Subsystem for Linux 2. In a nod to the fact that people work with different virtualization platforms, Microsoft has produced VMWare, Hyper-V (Gen2), VirtualBox and Parallels versions of the free VMs.

First detailed last year, Microsoft Dev Box is now finally generally available. This is Microsoft's "ready-to-code, cloud-based workstation optimized for developer use cases and productivity" and it comes from years of development building on Visual Studio Codespaces.

These preconfigured, container- and Linux-based dev environments served their purposes in 2019, but the demands of developers forced Microsoft to push things further. The result is Microsoft Dev Box, combining developer-optimized capabilities with the enterprise-ready management of Windows 365 and Microsoft Intune.

Although most people have long since moved on from Windows XP, some people are still running the ancient OS, even though Microsoft stopped supporting it way back in 2014.

Although the lack of support means continuing to use XP is a risky endeavor, it’s a stable and capable operating system that’s even able to run Windows 10.

There are plenty of virtualization tools to choose from, but if for anyone looking for one that offers solid support for a wide range of host and guest operating systems, it's hard to go wrong with VirtualBox. Bringing support for Windows 11 -- something previously available in the beta builds -- Oracle has now released VirtualBox 7.0.0.

As has been the case in the past, VirtualBox 7.0.0 is available for Windows, Linux and macOS (as well as Oracle's own Solaris), but this release is about more than adding full Windows 11 support. There are also new options for cloud-based virtual machine, as well as improved security and much more.

For many years the database has been at the heart of enterprise IT. But the shift to the cloud has led to massive challenges with migrations proving both slow and expensive.

A different way to approach this is to use virtualization, allowing existing applications to run on any modern cloud platform without being rewritten or replaced. We spoke to Mike Waas founder and CEO of Datometry, a SaaS database virtualization platform, to find out more.

Broadcom has struck a deal with VMware that will see the chipmaker buying the cloud and virtualization software firm for around $61 billion in cash and stock. As part of the acquisition, Broadcom will also take on $8 billion of VMware's net debt.

Since the launch of Windows 11, there has been a compatibility issue between the operating system and VirtualBox. People attempting to use Oracle virtualization software found they were unable to start virtual machines and saw error messages with Hyper-V or Windows Hypervisor installed.

As a result of this problem, Microsoft introduced a safeguard block which prevented people with VirtualBox installed from upgrading to Windows 11. But following work by Oracle developers to address the issue, Microsoft has now lifted the block.

Microsoft has made no fanfare about it, but the company has made available a virtual machine based on Windows 11 Enterprise that developers -- or anyone else -- can install and use free of charge.

A few days ago, Microsoft updated a page in the Windows Dev Center to include download links for Windows 11 VMs for VMWare, Hyper-V, VirtualBox and Parallels. The development environments have been designed to help users "start building Windows applications quickly" but they could be put to other uses instead.
