25H2 Breaking Powerpoint

[Seanc]

Has anyone else experienced PowerPoint presenting issues (it's one job) after 25h2

 

We are seeing staff when using Presenter view not get the expected output on 2nd screen Smartboards or Projectors and having to go to dulipcate.

If, whilst presenting, you use the options to switch screens it corrects.

 

Only notice issue this week Tues 07/10/25 , suspicious....

We have found this has started this week. PowerPoint 365 2502 (18526.20604). I've told teachers to use extended mode for now and switch back to duplicate when not using PowerPoint.

We have found if you set it to primary monitor instead of automatic(if your on duplicate) it works as duplicate. If your using presenter view then selecting the other screen as your primary monitor fix it and show the presenter view on your actual primary

I've had that issue this week, same solution as others suggested. Causing a bit of a headache

Hello all, 

This seems to do the trick, credit Helen W at https://learn.microsoft.com/en-us/answers/questions/5579683/powerpoint-presenter-view-not-showing-on-extended

Not a quick fix though.  An automated rip-off and re-install of office.  Might be useful for your more persistent staff.  Thank you Helen....

 

I've managed to fix it by rolling back to the previous update using the below in an elevated command prompt:

cd "c:\Program Files\Common Files\microsoft shared\ClickToRun" - hit enter

officec2rclient.exe /update user updatetoversion=16.0.19127.20240 - hit enter

This will popup an Office update box - let that run and once completed it should show the previous version in Word etc

Then disable office updates until Microsoft releases a fix

Are dual monitors at play?

This has now been fixed if you update to the latest version of O365.
