rdrcef.exe consuming high CPU after the April 2022 update

Question

I was using Adobe Acrobat Reader DC 2019. Everything was working fine. Whenever i launch any PDF files rdrcef.exe was not running (in task manager). Now i updated this with April 2022 patch update. Now whenever i launch any pdf, rdrcef.exe process is starting and consumes around 50-60% of the CPU.

I do not have any requirement for Adobe to connect to any cloud or even to the internet.

How do i stop this rdrcef.exe from running? Below are my PC details:

OS - Windows 10 64bit

Adobe version - 2022.001.20117 (April 12 2022 update)

Hi there

Hope you are doing well and am sorry for the delay in response.

As described rdrcef.exe was not running (in task manager) earlier but now after the updated this with April 2022 patch update the rdrcef.exe process is starting and consumes around 50-60% of the CPU.

Please try to repair the installation from the help menu (Win Only) and reboot the computer once and see if that works for you.

Also go to Edit > Preferences > Page Display > Under Rendering, uncheck 'Use page cache' > Click OK and reboot the application and check.

Regards

Amal
