Google Desktop Search (GDS) is highlighted as a powerful tool for Windows XP users, significantly outperforming the built-in search functions of the operating system. However, it poses serious security risks, particularly on shared computers, as it indexes files across all user accounts, allowing anyone with access to the PC to view cached content, including private emails and documents. Users have reported being able to bypass security measures of web-based email accounts and easily access sensitive information through GDS. This vulnerability raises concerns about user privacy and the effectiveness of Windows' account boundaries. Additionally, there is speculation about the transparency of Windows 95/98 systems when networked with Windows XP systems using GDS, suggesting that security measures may be ineffective in such configurations. Overall, while GDS offers impressive search capabilities, its potential to compromise user security is a significant drawback.
