Is there a way to identify what SQL Server Hotfixes are
installed on a server?

For the OS, this information can be located in the
registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows
NT\CurrentVersion\Hotfix

Which Registry Key would this information be stored in for
SQL Server Hotfixes. I scanned through my entire Registry
but could only identify for the OS level.

Someone had suggested using Microsoft Baseline Security
Analyzer. However, this tool only tells you what should be
installed in order to be security compliant... NOT, what
Hotfixes are currently installed on the server.

Thanks for your responses
