this happens with some updates on windows 10 , first write down the kb number of the update your having problems with then use this link
click here the top right search box type the kb number eg kb 12345
you will then see a list of all the different versions of the update you want , just make sure you choose the right one for your op system
now just follow the prompts , I can asure you this does work because I had a creator update that refused to fully install , using this web site it worked first time.
