Microsoft WebView2 is a special control for developers to embed web content into applications. It allows the latest improvements and technologies to use the Edge Chromium browser in different programs for Windows 10 and Windows 11, and WebView2 now supports thousands of applications, including Microsoft Office and Cerner.
Since Windows 11, Microsoft has built the WebView2 runtime into the operating system, but for Windows 10, developers have previously needed to distribute and install the runtime with applications.
Microsoft recently announced the introduction of the WebView2 runtime to a supported consumer version of Windows 10:
Redistributable runtime deployments allow developers to use WebView2 on devices that do not yet have a runtime, but this has been a pain point for WebView2 developers as development costs increase. Once we’ve completed the WebView2 runtime push that started today, developers can more reliably rely on WebView2 on Windows 10 or later consumer devices in addition to all Windows 11 devices, making the deployment of WebView2 apps more straightforward.
This announcement is not so important to the average consumer, after all, users do not interact directly with the runtime, they can get the necessary files to run a particular program at the same time as the installer. Microsoft pushed WebView2 to Windows 10 this time, mainly for the convenience of developers.
According to an article on the official website, the WebView2 runtime is currently available on consumer versions of Windows 10, with support for Windows 10 Home and Professional editions with version numbers 2004 and later. It has very little impact on disk space because the runtime is tied to the Microsoft Edge browser, which in turn is the default browser on Windows 10 and 11, which means that it takes up disk space for only one product. To ensure the best experience for users and to reduce pressure on Microsoft servers, Microsoft will push WebView2 in batches.
It is worth noting that this push is limited to consumer devices and does not affect domain-joined enterprise devices at this time.
