Description:
After I performed the Windows Update, I found that I cannot login to my MySQL Server, neither using MySQL Query Browser nor command line client. It says something like password incorrect, etc. I checked the Task Manager and the server is running. It runs just like normal.

So, I tried to uninstall the update one by one and found that after I removed the following item: 

Security Update for Microsoft .NET Framework, version 2.0 (KB928365)

the problem is solved.

How to repeat:
Performs Windows Update and include this item:
Security Update for Microsoft .NET Framework, version 2.0 (KB928365)

After rebooting the computer, you will not be able to login to the MySQL Server using any way.

Suggested fix:
1. Don't install the Security Update. (It's not good, right?)
2. Check what the Security Update crashes MySQL Server.
