Dw15.exe is part of Microsoft's "Error Reporting". It is embedded in IE6, and is included among the more recent updates to IE5.5. Kicking it out seems to do no harm. You could do a search for dw15.exe ... it'll probably show up in IE and in MS Works applications. Typically, its 150-160 KB in size. Delete it if you wish, then find and delete the following:
C: \ProgramFiles\InternetExplorer\1033\Dwintl.dll (version 10.0.2118.2. or higher)
C: \ProgramFiles\InternetExplorer\Dw.exe
( version 10.0.2118.2. or higher)
C: \ProgramFile\InternetExplorer\DW15.EXE
C: \ProgramFiles\InternetExplorer\Iexplore.exe (version 5.51.3 or higher)
(Delete then restore from the Recycle Bin after removing the others)
Remember to restore IE from the Recycle Bin once you've cleaned everything else out. Reboot, and it should be gone.
Microsoft offers a registry edit to disable error reporting, details

Before deleting or modifying anything,its a good idea to do a backup and to set a system restore point. Anytime you play with your registry, ALWAYS back it up before making any changes. For info on how to back up and restore your registry, see
