Report Problems shutting down PC in Emsisoft Anti-Malware Home Posted June 14, 2011 Hi Guys, This is well known MS bug. You can find hundreds if not thousands discussions all over the place Unfortunately MS itself admitted Currently there are no Microsoft Knowledge Base articles available for this specific error or event message Hi johnl, Well, sure please test what H_D suggested, but keep in mind that you have to turn all disabled features back "On" after all, since MSConfig can be used for testing purposes only(!) That is not a proper way to disable any Startup's / Services/ ... etc. You would rather use Autoruns by SysInternals I hope that you will find something using suggested MSConfig use (despite I have doubts) Further, definitely follow H_D's advice re: Mutual Exclusion Rules by any security in use If no luck - after all disabled by MSConfig are set back, please - Reboot and then - Reboot again in Safe Mode (F8) - Shut down Any differences? other than that … below are several points that worth to be considered & tested Usually the said error can be caused by: 1) Legacy Software in use . Do you have any, that is set to start with Windows?; 2) Please disable the following: - Hibernation (waste of resources... no less than...); - Fast User Switching – that is a major troublesome feature, which must(!) be disabled; 3) Please consider to install and use User Profile Hive Cleanup Service ; 4) Since you encountered the issues after EAM was installed, as far as I got it from your initial post, consider to disable Guard > File Guard Tab > “Protect PC even if no user logged on” There could be some other tips, but if you really wanna find out & pinpoint the cause - please be patient and follow the above one-by-one … meaning returning every and each option back if the issue persists Not easy, and time-consuming , but if you are really committed that will be a great help to other users, facing the similar trouble Cheers!
