Joaquim & Raffa76,
I have KB4550945 on my PC and laptop, but I think I am in the wrong thread for this multiple OFFICE WORD problem on startup. (45 instances of Word opened this morning - it seems to increase every day).
You may both have the WIN10 UPDATE problem but I think my problem is unrelated.
Can you provide your windows update log as a screen capture? Just save it as a .jpeg file and upload the picture?
I can't access your windows log update (see below).
You can see all my updates in my previous post to compare with yours.
From what I can tell, Win10 has different versions or different build numbers for a laptop and a PC.
My updates are for a PC @ Build 18363.815.
My laptop is at the same WIN10 update but it is at Build 18363.752.
My laptop DOESN'T have this multiple OFFICE WORD problem on startup yet it has the infamous KB4550945 update.
But my laptop says I have Microsoft 365 with Word not Office 2016 with WORD so that's a clue.
So, I think I have a problem with the last Office 2016 Update for PCs not the updates with WIN10.
What I am going to do is go to WORD on my laptop and send in FEEDBACK to MS there. I'll see what they say.
I'll check back here from time to time to see how things are going with the rest of you.
In response to everyone's complaints about the moderators, they are volunteers who are trying to help.
Cheers.
