DEANREILY

There are some comments at various sites on the Internet where users have reported OS crashes and loss of applications data when the files in "System queued windows error report" is cleared by disk clean up. They comment about GB sized content. My system is in use for a month and I see where my "System queued windows error report" has nearly 200 MB of content. I have not cleared these reports. When are these files cleared by reporting if I don't clear them? Should I be concerned about data loss or OS crash when I clear them. Suggestions of Registry changes are made to avoid this loss of data and OS crash. They say it is a bug in Vista.
