Hello,
Can we uninstall Microsoft Edge via Bigfix?
I suspect the answer is that you can’t.
Not because of a failure in Bigfix, but the Programs and Features tool (aka appwiz) doesn’t present any option to remove Edge.
Maybe the first question is “Can I remove Edge” and then “How can I do thte same using Bigfix” 
If MS do not allow a supported way to remove Edge then you’ll be hard challenged to do it via Bigfix or any 3rd party tool.
A quick Google (other search engines are available) I found this for Win11, so maybe its something that can be adapted into ActionScript methods to use as a fixlet. I do recall with some OS core features that they will re-appear following a release update so you may not find a permanent solution.
On newer versions of Microsoft OS, Microsoft Edge is Built-in (Chromium) and Internet Explorer 11 is no longer there
For newer/latest OS, I believe you can run a command to remove that feature.
