Hi all, I need help. I managed to apply SRP on a Vista premium machine through registry: https://www.wilderssecurity.com/showthread.php?t=232857 Now, I am facing a little problem. Everything is working fine & smooth, except IE (I tested with IE7 and IE when I am in my limited user account. IE doesn't even start. If I run IE with admin rights, it is working just fine. But upon normal execution, it can't. (Firefox works just great). BTW I installe office live and M$ Office applications keep on showing the very same welcome window of office live under LUA. What I mean is that maybe, for Office and IE, it has to do with registry keys which could not be updated on start (like runonce, btw, I did the trick to change the 3 runonce reg keys of ie to get rid of runonce problem without any result). In the same time, I can't see how SRP could interact with registry keys, when it is about application allowed to run ('cause they are in programs folder). The other possibility is that these applications call exes or dlls that are in the user folder... Does anybody have any clue of what is happening and could give me advices or even better a solution? SRP in Vista premium works great and it's a shame I have this odd problem... Thanks in advance.
