Enormous usage of the main memory by the RdrCEF process, which causes the computer to crash.

Hello,

several computers always download the latest update, which has been faulty for months, despite having adjusted the registry keys. Every update since 21007 has the same error and makes the software unusable.

If a computer has one of these Acrobat Reader versions installed and you try to open a PDF, you can observe in the Task Manager how the above-mentioned process devours all the RAM of the computer until it finally crashes. In addition the CPU usage is extremely high. 

The only solution is to install an old version of Acrobat Reader. Unfortunately, this is only a very temporary remedy, as it is almost impossible to deactivate automatic updates.

Will there be a patch in the near future to fix this problem? What exactly does the RdrCEF process do? Are there any settings in the software that influence it?

And yes, I already contacted the Adobe Support and got the following answer:
