What do you want to change in Edge. There are quite a few options now=
Or do you mean change the default?
If so, First install Chrome.
Then, there are settings to select your browser default, but, many have problems with that method, through the settings. The most successful way is:
Right click the stat menu orb and then the Control Panel.
Select Default Programs and, in the next window, "Set your default programs"
Scroll down and select Chrome as your default.
