    Microsoft have done a great job with Windows 10 in reducing the footprint of the operating system. On a 64 bit Windows 10 clean install, the total disk space in use is 9.48 GB, just under the psychologically significant 10 GB two-digit limit:

    Checking the "Compress this drive to save disk space box", you liberate a marginal amount of disk space, under half a gigabyte:

    We can check whether the NTFS disk compression limitation introduced with Vista's new security model is still present in Windows 10 by running DriveSpace with the NTFS compression algorithm. Indeed, almost a gigabyte and half is freed up, showing that Windows 10's "Compress this drive to save disk space" box is still unable to process protected system files:

    However, Windows 10 has introduced various new compression algorithms - 4K EXPRESS, 8K EXPRESS, 16K EXPRESS, and LZX - which aren't affected by the security permissions issue. We can also use DriveSpace to test the strongest of these algorithms, LZX:

    Converting from traditional NTFS compression (available on all Windows versions, even XP) to the new LZX compression (available only with Windows 10) has freed up more than an additional gigabyte of space.

    Let's see if we can squeeze Windows 10's footprint down even further, pushing the 5 GB range by invoking DoubleSpace now:

    Indeed, DoubleSpace, true to its name, frees up almost another gigabyte and half; reducing total disk space usage on a clean, 64-bit Windows 10 machine to just 112 MB above the 5 GB limit!

    All in all, it appears that Microsoft have done a great job with Windows 10 in significantly reducing its footprint.

    Using additional compression technologies built in to Windows 10 at the kernel level, you can further reduce the already small operating system footprint to just slightly above 5 GB.

    5 GB for a full operating system installation is nothing short of incredible, and would liberate about 11 GB on even the smallest, 16 GB eMMC "toy tablet" class devices.
