Windows crashes mostly because of third-party code

Microsoft has laid the blame for half of all Windows crashes on third-party code. Scott Charney, chief security strategist at Microsoft, told developers at the TechEd 2003 conference in Brisbane that information collected by Dr Watson, the company's reporting tool, revealed that "half of all crashes in Windows are caused not by Microsoft code, but third-party code."
Charney's comments come as the company highlights the rigor with which it tests its own products before release. Microsoft emphasized that products such as Yukon and Exchange Server were undergoing thorough testing--both internally and via independent third parties--prior to their release.
