Most are the same in Vista and Windows 7, but sometimes you have to manually add them. I usually add the REG files to make it easier for everyone so that they do not have to do it manually unless they wanted to.
For this issue, the main entry to look at is the NoSecurityTab DWORD. The locations above is the default location for this if the "Security" tab has been disabled, but it could have been manually placed (ex: by malware) in another location to still disable it.
