Win7 boot display user name or password error how to solve

Since the 32-bit system has always been a strike, so took the time to change the system to 64-bit. When everything is installed, thinkpa's fingerprint identification system can't be used normally. After referring to the online opinions, you need to create an admin user to use it, so I did it. But the result is still that virtue. The final solution to this problem is actually to install the vista driver. Sad reminder of lenovo. But when I restart the system, the system will automatically try to log in, and the user name and password are incorrect. Finding a lot of information on the Internet does not solve the problem. In fact, you can change it, but you will see this error every day when you turn it on. You have to click to confirm that you feel uncomfortable. After a long delay, you finally found a solution. I would like to share it with you.
The error message is as follows:

The solution is simple: type control userpassword2

in "run" and click OK.

This problem will be solved!
