Another issue that has been pointed out before is the issue with the corrupt digital signature detected during the pre-scan for 1703. Also, I might as well report (since I have experienced it multiple times now) that the "repair IE" fix actually doesn't break IE, it breaks edge somehow. After running the fix in version 1703, when you try to launch edge (no matter what manner of edge or app store reset I attempted, other than restore the registry), it just hangs on a white screen until it auto closes.
