Adobe Reader locking up - AcroCEF.exe using 100% CPU

New Here ,
Aug 10, 2022 Aug 10, 2022

Hi All

Just on a month ago now we have been battling an issue that is affecting all of our Windows 10 64bit Machines.

When a user opens up a pdf file Acrobat opens many AcroCEF.exe sub process and one of these starts to take up nearly all CPU and memory starts to increase to over 4GB or more depending on the machine.
Then the screen goes blank and locks the computer as it runs out of resources.

We have been trying to pinpoint what might the issue be and any changes to the environment but have been unsuccessful.
The only things that have changed is Windows Updates as normal are being rolled out, we deployed a Product Called Ring Central as our Phone system and also some poly headset software which now has subsequently removed in attempt to roll back any changes but again no difference to the outcome.

For many users we were able to change Edge as the default and got them work but even then some reason adobe still opened the update process and crashed the computer so we had to full uninstall.

We have Adobe deployed by GP and are running version 22.002.20191

Any guidance here would be appreciated as it’s been a real issue for the business with over 100 people affected.
