On most installations of Windows 10 the 1607 update installs without a problem. It just happens to be that my laptop is not most installations. For one, I am using deduplication which is a server feature not to mention all my developer tools.
After installation, my deduplication stopped working which I fixed with new 14939 packages and none of my store apps worked. I fact my store didn’t even open.
Managed to fix store by running wsreset.exe after which I could repair all my apps
