Users that upgrade Windows Vista OEM computers to Windows 7 may “notice that manufacturer-specific recovery applications are no longer available on the System Recovery Options menu.” Its because some OEM preload the Windows Recovery Environment (known as the System Recovery Options in the UI and help topics) on systems. Very frequently, these Windows RE tools are customized to include manufacturer-specific recovery applications that can be accessed from the Windows RE tools menu. When these systems are upgraded to Windows 7, the manufacturer-preloaded Windows RE option will be replaced with a Windows 7-compatible Windows RE.
