What's the difference between Windows 11 22H2 and 23H2?
Microsoft released an update to Windows 11 recently that caused confusion. The core problem with the company's strategy was shipping two Windows 11 updates with similar feature sets but that have different names. The fact that Microsoft doesn't use a consistent naming scheme when discussing its updates hurts matters further. The end result was an update to Windows 11 version 22H2 rolling out just before the release of Windows 11 version 23H2, which became available today. Those updates include many of the same new features, such as Copilot.
Everyday computing won't change much based on which of these two updates are installed. But the situation still causes confusion. Our Senior Editor Zac Bowden broke down the odd reasoning behind Microsoft's Windows 11 23H2 Update.
The Windows 11 23H2 update that first shipped a few weeks ago is an optional update. As such, people can push it back and not have it installed on their PCs for quite a while. In contrast, since Microsoft rolled new features into the Moment update for Windows 11 22H2, more people will have access to Copilot and a plethora of other options.
