Microsoft uses ESD files because they use "solid compression," where files are streamed together as one large blob for better efficiency. This typically reduces a 5GB installer to roughly 3.5GB. Third-party creators often use experimental tools like KGB

Third-party creators often use experimental tools like KGB Archiver or 7-Zip with extreme settings (LZMA2/PPMd). While these can technically reduce file sizes further, decompressing them can take hours or even days and often results in corrupted data. The Major Risks

Unofficial ISOs are frequently embedded with malware, trojans, or spyware . Because the OS is the foundation of your computer, a compromised version can steal passwords or enlist your PC into a botnet before you even install an antivirus.

If hardware resources are low, consider a lightweight Linux distribution instead of a potentially dangerous "highly compressed" Windows image.
