win10 default browser in background?

i'm currently using Opera browser ,and noticed after a couple days it gets very slow to open up, even after i cleared all history cookies and what nots.
then i went to Revo - tools- browser cleaner - and delete everything in IE , FF , chrome and Edge...even though i never use those browsers . In fact the only other browser on this PC is Edge .
After the clean , Opera is flying again.
How does that work ?

Hello @3nd,

I have noticed that you have NOT had ANY replies, so I thought that I would try and help.

NOT a full solution, but worthwhile doing as a start from here on in. For I.E. [ Turn Off Windows Features ] and Edge, you could turn them off or disable them [ that's what I normally do ]. There are Tutorials for those.

I hope this helps.
