Given the large size of the official suite, a dedicated community of software enthusiasts and "repackers" emerged, creating custom builds known as "lite," "slim," "repack," or "green" (portable) versions. These are the sources of the "100MB" claims. They are not official Microsoft products but rather modified versions of the original software.
: Even if the file isn't malicious, extreme compression often results in corrupted executables that will fail to install or run properly. Safe and Legitimate Alternatives
Users seeking accessible productivity tools do not need to rely on risky, highly compressed downloads. Several safe, legal, and free alternatives offer full functionality without compromising system security:
When an installer is actually 100MB, it is never the full, untampered software. Major Risks of Highly Compressed Software ms office 2016 highly compressed 100mb exclusive

is a free, open-source file archiver that uses its own 7z format and the LZMA (Lempel–Ziv–Markov chain algorithm) and LZMA2 compression algorithms. These algorithms are known for their very high compression ratios, often outperforming the standard ZIP format. To achieve "ultra" compression (the -mx=9 setting in 7-Zip), users might enable settings like "Ultra" compression level, large dictionaries (e.g., 128MB, 256MB), and the BCJ2 preprocessor for executable files.

Often, these compressed files are "portable" versions. These are designed to run from a USB drive without a full installation. While they can work, they often lack full functionality, suffer from bugs, or fail to integrate properly with the Windows operating system.
The installer itself (setup files) is rarely below in compressed .iso or .exe format — even with high-efficiency compression tools like 7-Zip (LZMA2) or WinRAR.

Downloading "highly compressed" software from unofficial sources carries significant risks: : Repackaged files often contain trojans or keyloggers. System Instability : Missing DLL files can cause frequent crashes. Activation Issues : These versions often lack legitimate licensing paths. Update Failures
It is technically impossible to compress several gigabytes of complex software into 100MB while keeping it fully functional.
Avoid the temptation of "highly compressed" executables. The risk of malware, data theft, and system instability far outweighs the convenience of a small download size. Protect your digital life by sticking to official distribution channels and verified open-source alternatives.
To achieve a 100MB file size, creators of these modified packages must alter the core software. This reduction is typically done through two main methods:
