Hi guys, I have signed up specifically to thank Dave H for his solution to the problem of Office 2010 modules not opening on XP after the latest Windows updates.
Before I found this thread I was about to uninstall MS Office and replace it with OpenOffice instead (I might still do that!).
Now that I have removed KB4461522 everything has returned to running as it should.
Thanks once again, Dave, and I hope all others in the same predicament will find your fix.
