how do i uninstall mysql in windows 10 including my.ini?

[Karen Goh]

I ran into error code - can't connect to MYSQL on localhost (10061) after I added a line in my.ini.

# The default character set that will be used when a new schema or table is
# created and no character set is defined
character-set-server=utf8
default-character-set=utf8mb4

So, what I did is uninstall MYSQL5.7 and installed a new version - MYSQL 8.

The problem is that it is using msi.installer and the older configuration files still stays put and so the new version will be making use of this old file.

I'd like to seek help how to get rid of the old configuration file in windows 10 so that I can use MYSQL 8 in a clean slate.

Tks.
