If you have a look at the update in the Microsoft Update Catalog at the following URL, you’ll notice that it has been updated – the name and the KB reference has been updated;
https://www.catalog.update.microsoft.com/ScopedViewInline.aspx?updateid=a9262201-26d9-464b-ab32-106e4652db0c
Therefore the reinstall is due to this.
Sure enough, the Microsoft Update Catalog shows it was last modified on May 4. If you go to the usual Update Catalog URL, you can see three different versions of the update, for 32-bit and 64-bit Win10 1607, and one for Server 2016 64-bit.
