After downloading a critical update, several of the machine's I maintain ( all are the same type and configuration ) have the " Windows Explorer Has Encountered A Problem And Needs To Close " message and wants to send the info back to Microsoft. I have looked at the deails of the error and only have been able to get an exception code 0cx0000005. I first googled the error with no definitive results. The same thing going to microsoft knowledge base. The machines run, but only after the message pops up several times. Any ideas as to get rid of this annoyance ?
