But it turns out this isn't enough to bridge the compatibility gap. If every Edge user were using the very latest version of Edge, it wouldn't be so bad, but that's not the case, and that's because of how Microsoft has bundled Edge with Windows 10. Most home users will end up running the latest feature update to Windows 10 within a few months of its release. But enterprise users are more diverse. An enterprise that has rolled out Windows 10 version 1709 to 10,000 seats may follow that by deploying version 1803 to another 10,000. The systems with 1709 will stick with 1709 — after all, it's still supported — as the enterprise focuses its resources on getting legacy systems onto "some version of Windows 10," rather than getting every Windows 10 user onto the same version of Windows 10.
The result is that all those compatibility, stability, and feature improvements made in versions 1803 and 1809 will be completely off-limits to the machines running 1709. This means that Edge, already a relatively small target for Web developers to think about, suffers major version fragmentation. Contrast this with Chrome, where within a few days of a new version coming out, almost the entire user base is migrated.
This coupling with Windows 10 similarly means that there's no facility to offer Edge to Windows 7 or even macOS users.
It's this issue that's perhaps the lethal, killer blow for Edge. If every Edge installation were always the latest and greatest one, and if corporations could standardize on Edge across their entire fleet — including Windows 7 systems, including Macs — then the browser might just have been a big enough, consistent enough target that it would be sustainable. But Redmond has decided that it isn't. Microsoft did consider decoupling the browser from Windows 10 so that it could be updated on its own cadence and so that it could be ported to Windows 7 (if not macOS), but for reasons that are unclear, it decided that the work to do this would be too substantial.
