Windows Update keeps offering KB4025252 (Cumulative security update for Internet Explorer: July 11, 2017) over and over and over again – even though it's already installed.
We've seen this on two PCs so far, both Windows 7 Professional 64-bit.
Looks like we're not the only ones seeing this: https://social.technet.microsoft.com/Forums/windows/en-US/3c713cd6-87ba-4908-bc06-fef248dcbd26/kb4025252-security-update-for-internet-explorer-11-install-multiple-times?forum=w7itprosecurity.
Is there a solution to this, other than waiting for Microsoft to fix yet another botched Windows Update?

This was a benign bug by Microsoft. Since the changes are already included in the July Security Monthly Quality Rollup (KB4025341), the patch wasn't detecting that the patch was no longer required:
Per this forum thread, Microsoft released an updated version of the patch via WSUS if you want to perform a manual synchronization. Otherwise, you'll pick it up on your next scheduled sync.
I tested it myself, and it's no longer showing up on my PC as a necessary patch.
