Extensively used IE9 Developer Tools and I just updated to IE11 "11.0.2" and the Developer Tools are garbage.
My Network and Profile Tabs are blank. Is there a "special" setting that I'm missing in order to enable them, or could there be a specific windows hot fix between the IE11 RTM and 11.0.2 that I may be missing?
This helped me for IE 11, Windows 10:
sc config diagnosticshub.standardcollector.service start=demand
(see https://www.systemcamp.com/network-collection-agent-failed-to-start-in-ie-11-or-edge/)
For me, Network tab stopped working one day and following worked:
Restart Microsoft (R) Diagnostics Hub Standard Collector Service
