Windows 95 identified setup programs by matching executable names against a list of keywords, as revealed by Microsoft engineer Raymond Chen. This heuristic aimed to protect system files from being overwritten by installers, which was a common issue during that era.
Windows 95 detected setup programs by reading executable filenames and comparing them to six hard-coded keywords: setup, install, inst, imposta, ayarla, and felrak. This approach helped identify installer programs and trigger the system's repair routine for damaged files.
Installers during the Windows 95 era often overwrote important system files without checking file versions, leading to potential system instability. The operating system implemented a backup mechanism to safeguard against such overwrites, storing copies of commonly affected files in a hidden directory.
The heuristic relied on accurate filename detection, allowing programs with atypical names to slip past the identification process. Consequently, an installer with an unusual name could bypass the recovery mechanism, while an unrelated executable named 'instant.exe' could trigger it without cause.
With the release of Windows 2000, Microsoft introduced a more sophisticated approach for managing file replacements during installations, addressing the shortcomings observed in Windows 95's heuristic methods.
