The bloated size of these unnecessary Win10 'features updates' required me to use an additional external memory temporarily, before the last update would install to my Lenovo 100S with its small internal memory. Nothing was left on the external memory afterwards, fortunately. Then disk clean up got rid of several GB of the previous Win10 installation.
Lenovo and others must have sold thousands of such small-screen 2GB RAM, 32GB storage laptops - so there must be quite a few owners baffled by Win10 updates...
