I am not posting a lot about tweaking Windows, so please appreciate this one 
When I have to use Windows I only use it in a VM on my Mac with Parallels Desktop. These machines are just tools to develop with HCL software, so security is something I care less in this setting. I wondered if it's possible to login automatically to the Windows VM - and actually it is.
Open the Registry Editor and navigate to the key as shown in the screenshot.
Then create new String items with the following values
- AutoAdminLogon = 1
- DefaultDomain = leave blank
- DefaultPassword = user's password
- DefaultUserName = user name
Restart your machine / VM and watch the auto login does it's job.
