Downloading a "highly compressed 10MB" version of Microsoft Office 2016 is a high-risk activity that is almost certainly a scam or a vehicle for malware
is technically nearly impossible without losing critical components.
Compressing 4,000 MB into 10 MB would require a 99.75% compression ratio — far beyond what any real compression algorithm (ZIP, RAR, 7z) can achieve. Lossless compression simply cannot work miracles.
