Where can I find an updated guide on the registry keys and entries of the latest version of Microsoft Security Essentials for all versions and editions of Windows 7 SP1?
There is no updated guide for registry keys and entries for MSE (I presume you mean MSE uninstall information) - the present Wiki
If you mean installation keys and entries information, AFAIK, this is not available.
MSE cannot be used on Windows 8.x.
Did this solve your problem?
Sorry this didn't help.
