I have this problem when I'm either in 'Safe Mode' or when I've used 'msconfig' to go into diagnostic mode. When I try to log out Windows says there is a program called 'Sample' which is not responding. If I tell it to just go ahead and log out anyway, it does. Oddly enough, if I look at the running processes using the Task Manager (or Itty Bitty Process Manager) there is no 'Sample' process running.
Also, I have found in the Windows log, an entry with event-Id 1517 for every time this happens (I copied the description from eventid.net, since mine is in Swedish):
"Windows saved user <user name> registry while an application or service was still using the registry during log off. The memory used by the user's registry has not been freed. The registry will be unloaded when it is no longer in use. This is often caused by services running as a user account, try configuring the services to run in either the LocalService or NetworkService account."
After some Googling I found a MS tool called 'User Profile Hive Cleanup Service' which apparently can be used for these issues by terminating 'left-over' applications at log-out (or something like that). The reason I haven't tried it yet is that the name 'Sample' sounds kind of fishy to me so I suspect it might be something more malicious than an ordinary program not finishing up as it's supposed to.
I have tried searching my computer for executable sample.* files, but found nothing. I have run AVG Free, Panda Online Scan, Housecall, Adaware, Spybot, CWshredder and ewido.
Update: Ok, I found it. Intel's PROSet is to blame. I uninstalled it which got rid of the problem in "Safe Mode". When I installed the newest version instead, the problem was back, so it's not exactly solved but at least it does not seem malicious. Can I do something to get rid of the "Not responding..." messages in "Safe Mode"?
