As part of installing SQL Server on my PC I've created a specific user for it. When I log in now I'm offered this user as well as my own account. I remember in older versions of the Windows NT series there was an option in the user config dialog to set the user as non-interactive so they couldn't log in. I can't seem to find that checkbox in the Vista equivalent. Is there any other way to achieve this?
This article explains the Windows XP solution which also works in Windows Vista and 7.
It requires you to do some registry editing so be extremely careful when doing this.
If you want to disable the account you can edit the local policy as follows.
