I really don't like the new revision of Shutdown in FCU which opens apps upon resume. Shift + Shutdown which is supposed to do Full Shutdown doesn't work either. I do know other ways for this. But still, I'm looking for group policies or Reg keys that disables this behavior, at least for Shutdown. It does make sense for RESTART (sometimes), but why SHUTDOWN!!! I came across this reg key which I think probably is responsible for this behavior. So, I changed it to 1 and upon restart this key automatically resets to 0 and all the opened apps still resume themselves. Tried several times, but still the same s**t. So, before I give up, I would like to know what exactly this key does? Code: [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shutdown] "CleanShutdown"=dword:00000000 Thanks!
