Tiny Core Linux can fit in 20MB. Add a Windows theme, and you have a convincing fake. Part 3: How Extreme Compression Actually Works (Without Magic) If you want to legitimately shrink a Windows installation media, here are the real tools and limits: Using Compact OS (Built into Windows 10/11) Microsoft’s built-in compact.exe with the /compactOS:always flag compresses system files using the XPRESS or LZX algorithm. This can reduce a fresh Windows 10 install from ~20GB to ~12GB. Still light-years from 50MB, but useful for low-storage devices (e.g., 32GB tablets).
But does this tiny, miraculous file actually exist? And if it does, what on earth does it do? windows 10 highly compressed 50mb

Anyone promising 50MB is either lying, selling a virus, or selling a glorified bootloader that prints “Hello World.” The dream of a 50MB Windows 10 stems from a noble desire—breathing life into old hardware or saving precious disk space. But chasing that dream on shady forums will only infect your machine or waste your time. This can reduce a fresh Windows 10 install
