I have upgraded to Windows 10; had a great experience on installation process. But very strange thing is I am not finding a way to pin (ctrl+9 for IE) the Developer Tools to an existing window with the MS Edge browser app. Is it missing?
Correct, pinning/unpinning the F12 developers is not available in current builds of Microsoft Edge (10240). This is a known issue and we are planning to bring it back in a future update.
In my laptop, the Microsoft Edge has it pinned. And the icon with the shoutcut (Ctrl+P) is back too.
Microsoft Edge 25.10586.0.0
Microsoft EdgeHTML 13.10586
And in my desktop it's still missing, but looking at the version...
Microsoft Edge 20.10240.16384.0
Both PCs are fully updated, but the thing is that in the Desktop I'm getting Insider Preview updates, and in the laptop I'm not.
