I get the impression that every time MSE updates, the old 'update engines' are deleted and replaced with new ones for the update process. So even if you delete what's there now, the next time MSE updates it will install new ones. If these entries are causing no performance issues there is really no reason to remove them as they will just come back. This may be a flaw with the latest version of MSE and will be addressed by Microsoft with a program update that will delete them after the update. MSE has probably always installed these for the update but then deleted them after their use. I no longer use MSE so I can't really say for sure. I prefer AVG and use the 'free' version because it scans for and removes most Tracking Cookies. Just paranoid about Tracking Cookies, I guess. The only annoying thing about AVG is that it now includes something called PC Analyzer. PC Analyzer is a Registry Cleaner that can potentially harm your system and there is no way to totally remove or de-activate it. If you want to continue using MSE, I'm told it is a very good security program and many members here like it and recommend it. So, other than the glitch in the Device Manager entries, your system is well protected. If you want to investigate further, you could post a question or browse the Microsoft Answers forum for other users with the same concerns. I hope I've answered your question in a professional manner and wish you luck with Windows 7 and your PC. George.
