I usually enter sql by typing:
mysql -u root -p

it then asks me for my password and i enter it though when i restart my computer and do the same thing it says:
Access denied for user 'root'@'localhost' (using password: YES)

And i end up having to change the password again to log in. Though when i restart the same thing happens.

Is there anything im doing wrong?
Im running SQL on windows. I used the installer. Im using XAMPP and i turned SCV off with the XAMPP control panel but i start sql via the panel. and i am sure its "running"
