How can I tell if SP6a is installed, using the registry

Posted by Ali on June 20, 2004 No comments

The standard method of inspecting the CSDVersion value name at
HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows NT/CurrentVersion does not show the a, showing only Service Pack 6.

If Service Pack 6a has been installed, the Installed value name at
HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows NTCurrentVersionHotfixQ246009 will contain a 1.
