Aggressive compression of system files has been linked to data corruption issues, particularly when disk maintenance utilities interact with compressed system volumes. Microsoft itself documented a memory leak issue specifically related to compressing Windows image files on Windows 8.1 systems.
All languages except for a single default language (usually English) are removed. Windows 8.1 Highly Compressed 600mb
The Windows imaging format (install.wim) is converted into a highly encrypted Electronic Software Download (install.esd) file using maximum compression algorithms. This process requires heavy CPU power during decompression but shrinks the initial download package down to its absolute limits. What Is Missing in a 600MB Windows 8.1 ISO?
They often use advanced compression algorithms (like .ESD or high-level .WIM compression) to shrink the remaining files to their absolute limit. Aggressive compression of system files has been linked
A true 600MB version is not a daily driver. It is a "tinkerer's toy" or a recovery rescue disk.
