You know, this is a useful tool when you're clearing a malware infection. Everyone seems to be assuming this is fully automatic, but it requires you to accept the change before it commits.
Of course, since everyone here is rabidly anti-Microsoft, anything MS does is automatically the worst thing in existance.
Edit: In this case, it is providing the option to reset Edge's search and home settings back to "known safe" defaults. If you had this tool let you set anything, that's an attack surface that can be exploited by a "tech" from India or a malware running counterops to prevent removal.
Worst case, you use another browser, since clearly Microsoft is the devil and you shouldn't use Edge anyway.
