Okay,
I also have these two problems (error phpmyadmin's incorrect parameters; check host, username, password + impossible to change the root password fonctionnality ← what is the mysqladmine.exe command line running? + "ERROR 2003 (HY000): Can't connect to MySQL server on '127.0.0.1' (10022 "Unknown error")" when launching mysql console).
I add, that a nestat -ano shows that mysqk_z.exe is listening on 127.0.0.1:3306, and that the mysql.err log has ...no error:
"[snip]

I've installed\tested the versions 11_0_1_ZeroXI.exe, 11_6_0_ZeroXI.exe, 11_7_7_ZeroXI.exe, 11_7_8_ZeroXI.exe, 11_8_1_ZeroXI.exe, 11_8_2_ZeroXI.exe, 14_0_1_ZeroXIV.exe ==> I've got the same messages.
ps: my hosts file contains only one line (127.0.0.1 localhost), I've searched to verify that I have only one my.* file which is the one present in the UniServerZ directory, and I've uninstalled any other program that would have a distant relation with mySQL.
==> Any idea how to investigate further ☹️ ?
Regards.
