You can disable dwwin.exe which is a Dr. Watson error-collector and reporting tool, in your registry like so:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\AeDebug
or you can download dwwin.exe to try to repair it, here:

Otherwise, try also doing WINDOWS UPDATE from the "TOOLS" option at top of IE menu .
