What's the download size of the Windows 10 Fall Creators Update?


The Windows 10 Fall Creators Update (version 1709) is around 2.65GB using Windows Update. However, it all depends on the version (1703, 1607, 1511) and platform (32-bit or 64-bit) you’re running, because using the Microsoft Unified Update Platform (UUP), only the files required to upgrade your device will be downloaded. As a result features updates can be up to 35 percent smaller than downloading the full installation files.

The Windows 10 Fall Creators Update ISO file is 4.4GB for the 64-bit version, while the 32-bit version is 3.2GB.
