MySQL 5.7 Release Notes
There are two approaches for upgrading MySQL on Windows:
Using MySQL Installer
Using the Windows ZIP archive distribution
The approach you select depends on how the existing installation was performed. Before proceeding, review Section 2.11.1, “Upgrading MySQL” for additional information on upgrading MySQL that is not specific to Windows.
Upgrades between milestone releases (or from a milestone release to a GA release) are not supported. Significant development changes take place in milestone releases and you may encounter compatibility issues or problems starting the server. For instructions on how to perform a logical upgrade with a milestone release, see Logical Upgrade.
Performing an upgrade with MySQL Installer is the best approach when the current server installation was performed with it and the upgrade is within the current release series. MySQL Installer does not support upgrades between release series, such as from 5.6 to 5.7, and it does not provide an upgrade indicator to prompt you to upgrade. For instruction on upgrading between release series, see Upgrading MySQL Using the Windows ZIP Distribution.
To perform an upgrade using MySQL Installer:
Start MySQL Installer.
From the dashboard, click Catalog to download the latest changes to the catalog. The installed server can be upgraded only if the dashboard displays an arrow next to the version number of the server.
Click Upgrade. All products that have newer versions will appear in a list.
NoteFor server milestone releases in the same release series, MySQL Installer deselects the server upgrade and displays a warning to indicate that the upgrade is not supported, identifies the risks of continuing, and provides a summary of the steps to perform a logical upgrade manually. You can reselect server upgrade and proceed at your own risk.
Deselect all but the MySQL server product, unless you intend to upgrade other products at this time, and click .
Click to start the download. When the download finishes, click to apply the updates.
Configure the server.
To perform an upgrade using the Windows ZIP archive distribution:
Always back up your current MySQL installation before performing an upgrade. See Section 7.2, “Database Backup Methods”.
Download the latest Windows ZIP Archive distribution of MySQL from http://dev.mysql.com/downloads/.
Before upgrading MySQL, stop the server. If the server is installed as a service, stop the service with the following command from the command prompt:
C:\> NET STOP MySQLIf you are not running the MySQL server as a service, use mysqladmin to stop it. For example, before upgrading from MySQL 5.6 to 5.7, use mysqladmin from MySQL 5.6 as follows:
C:\> "C:\Program Files\MySQL\MySQL Server 5.6\bin\mysqladmin" -u root shutdownNoteIf the MySQL
rootuser account has a password, invoke mysqladmin with the-poption and enter the password when prompted.Extract the ZIP archive. You may either overwrite your existing MySQL installation (usually located at
C:\mysql), or install it into a different directory, such asC:\mysql5. Overwriting the existing installation is recommended.If you were running MySQL as a Windows service and you had to remove the service earlier in this procedure, reinstall the service. (See Section 2.3.5.8, “Starting MySQL as a Windows Service”.)
Restart the server. For example, use NET START MySQL if you run MySQL as a service, or invoke mysqld directly otherwise.
As Administrator, run mysql_upgrade to check your tables, attempt to repair them if necessary, and update your grant tables if they have changed so that you can take advantage of any new capabilities. See Section 4.4.7, “mysql_upgrade — Check and Upgrade MySQL Tables”.
If you encounter errors, see Section 2.3.6, “Troubleshooting a Microsoft Windows MySQL Server Installation”.

I hope can help at someone.
my.ini did't overwrote and contained these lines:
[client]
password = something
From this point I lost _ALL_ access to MySQL:
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
I mean mysql.exe or mysql_upgrade.exe also didn't worked.
I figured out the problem was the password line in my.ini. I did commented out temporarily, ran mysql_upgrade.exe then I did uncommented then everything worked well.
To those who want to remove my comment, read the following first:
Please refer to
http://docs.oracle.com/cd/E17952_01/refman-5.1-en/windows-install-wizard.html#mysql-install-wizard-upgrading
In section 2.3.3.1.6 of that article, please pay attention to the 2nd paragraph that I include here below:
Automatic upgrades are available only when upgrading between installations that have the *same major and minor version numbers*. For example, you can upgrade automatically from MySQL 5.1.5 to MySQL 5.1.6, but not from MySQL 5.0 to MySQL 5.1.
As a matter of fact, I have MySQL 5.1.30 in a test computer. I run MySQL 5.5 setup WITHOUT previously uninstalling 5.1. Result: both versions are displayed in "Add/Remove Program" applet (and the new server is not using old data, but this is another topic)
