By default, Windows 10 Technical Preview builds take 16GB of disk space. But what if your new build requires much more space than the previous build? In that case, you’re facing a bug, and this issue needs to be solved.
Over-sized installation of recent builds could cause various problems. For example, you won’t be able to install it due to insufficient disk space. Or it will take much more time to install than it should, some users report that it took them up to hours to install the new build.

In some cases, this bug is causing setup to download all available language packs during the installation of new builds of Windows 10 Technical Preview. Besides disk space and installation time problems, this bug could also make a few unexpected and unwanted folders appear on your desktop or in File Explorer.
