Windows 95 defenses against installers that overwrite a file with an older version
Summary
The article explains how Windows 95 defended against installers that overwrote files with older versions by using a SYSBCKUP directory and post-install checks to restore or preserve the correct components. It contrasts early blocking methods with a cleanup-after-install approach to avoid user-facing failures, and notes practices like component-specific installers and VerInstallFile.
