Second part, 1.00 GB, of a split RAR set that packs a single-language Windows 10 Pro installation labelled pre-activated. Nothing inside can be recovered from this volume alone: extraction starts from part1.exe and requires parts two through four sitting next to it. An OS image is useful after a storage replacement or board swap for testing a repaired laptop, though third-party pre-activated builds are unofficial, so confirm the source, check for tampering and respect licensing terms.
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.
