Second of three RAR volumes, 1.42 GB, that together hold a Windows 7 image whose edition and bitness are not stated in the name. It cannot be extracted separately and depends on the self-extracting part1 and the short part3. When rebuilt, the image can be written to USB or DVD for installing Windows 7 on legacy hardware during repair or testing. As the release origin is unknown, verify integrity, scan for malware and ensure a valid licence before installing it.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @laptopschematics. Enginerys does not host this file.
