Application error 0xc0000942

Appears every time I try to open an Windows application (EXE, WORD, PP etc).  From what I've found this was a problem last year and all subsequent updates should have solved.  

Funny enough the fix I found online:  

This issue is fixed in Monthly Channel Version 1803 (Build 9126.2116) or greater. To get the latest update immediately, open an Office app and choose File > Account > Update Options > Update Now.

If I could open the App then I wouldn't have the problem!!!
