Third volume of a split RAR archive holding a Windows 8.1 Pro image, 1.00 GB. This piece is useless alone: all volumes, from the self-extracting part1 through part4, need to be present together for the extractor to rebuild the full contents. After extraction the image can be prepared on a USB drive for installation or testing. A checksum or CRC error during extraction points to a corrupted volume. Keep official licensed media for customer machines.
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.
