After upgrade to Windows 10, I can't get the F12 Developer Tools to show / work under MS Edge.

IE 11 developer tools do still work, but I can see rendering differences on my websites I am working on between them, so could do with getting them working under Edge.

I am presuming they are available??

Have already tried the re-register packages fix, as well as reset Internet Options, but nothing works.

The following issue page contains a solution for this in the comments, which worked for me: https://developer.microsoft.com/en-us/microsoft-edge/platform/issues/18153935/

If you are allowed to use powershell, execute the following command as your user to fix the dev tool: Add-AppxPackage -register "C:\windows\SystemApps\Microsoft.MicrosoftEdgeDevToolsClient_8wekyb3d8bbwe\AppxManifest.xml" -DisableDevelopmentMode -Confirm:$false
