Re: how can i rollback the windows 10 au update on my acer one 10? i already deleted the old version

my acer one 10 s1002 came up with windows 10 32bit OS... i want to clean install my windows 10 32bit with the OS that came with it(the one WITHOUT/BEFORE the aniversary update), because currently my OS is updated with the aniversary update from windows. i cant restore on my previous version of windows in the "Update and Security -> Recovery" and when i try to factory reset my unit, the OS remains as windows 10 with the aniversary update...
i want to know how to install the default windows 10 32 bit WITHOUT/BEFORE the aniversary update...
