On modern computers, Dw.exe is the code name of a Microsoft tool called Dr. Watson, installed by programs like Microsoft Money, Office XP and some installations of Office 2003. [research by a Wikipedian and Microsoft paid support back most of this up.] Some bulliten board postings and help articles on computing.net indicate it to be the cause of many error messages predominantly when booting up the operating system. The solution is to delete dw.exe, and repair your Office installation. For Office XP, this requires the CD. For Office 2003, it does not.
In computing, it is generally safe to delete a corrupt module, especially if the host application continues to run or regenerates the needed file.
dw.exe is also called dw15.exe, and dw20.exe. The name change represents upgrades to the process. dw15.exe was found by one Wikipedian to be associated with MS Money. dw20.exe was found by this same Wikipedian to be associated with later versions of Office, specifically 2003.
iedw.exe causes error messages related to the invocation, use, or purging of the iexplore.exe interface into or out of memory. In colloquial terms, the launching of Internet Explorer. According to the Microsoft knowledge base, Internet Explorer no longer has a repair function as of Windows XP. You can install a previous version that did not ship with the operating system, or reinstall the OS to continue using Internet Explorer. Other web browsers do not use this process.
Very rarely on modern computers, dw.exe appears as a virus. More commonly if the above solutions fail or are inapplicable, it could be spyware. See antispyware and antivirus and malware for further reading.
