Adobe Reader X (AcroRd32.exe) process keeps using high cpu

I ran into this problem on a Terminal Server configuration where the Adobe Reader X (AcroRd32.exe) process keeps using high if not all cpu capacity even after you close the program. After some searches I found this could be because the welcome screen that is opened when you start Acrobat Reader isn’t closed at all, the session stays active and keeps using a lot of cpu capacity.

I could not found a fix for the problem at this time , but there is a workaround that solves the problem. You can disable the welcome screen from starting with a registry key.

1. Open the regedit and navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Adobe\Acrobat Reader\10.0\FeatureLockDown

2. Add a new key with the name: cWelcomeScreen

3. Add a DWORD value to the key: bShowWelcomeScreen with value 0

Now when starting Adobe Reader it will not start the welcome screen but also does not uses the high cpu.

    I have Reader 11 (verions installed. When I open and close the application there is still an Adobe process running. On my Windows XP machine, it takes over 100% of processing and the CPU fans kicks into high gear!

    I found that if I changed the properties of AcroRd32.exe, the process quit when the application closes. Select the Advanced button on the General tab and uncheck the Archive/Indexing attributes.

  2. Hi, nice post! I had exactly the same problem with Adobe Reader 11.0.7 on our RDP servers – always 25 % CPU load for each user. Problem was solved with the reg entry. Additionally I had also to uncheck the Archive / Indexing attributes like sachin wrote. And it works…

    Thanks for sharing!

  6. Another way through the closing process of loading system. There is then no need for any changes to the registry, parameters or settings Acrobat Reader. Batch script prepared by default closes Acrord32.exe process and to this end has been designed, but the script can be used to close as any other process too burdensome system, which was suspended when the script calls to the appropriate parameter. If this parameter contains a long name with a space, you must enclose the parameter in quotation marks.
    Inside the script, to the beginning of the several parameters can be determined, for example. Time of suspension, the time of re-checking, or where the report is to be created (LOG). The script closes all processes meet the criteria for any user, of course, not the system that can not be closed. While not closing speeches AcroRd32.exe processes that are operating normally, that does not block the normal use Acrobat Reader. Lockable only those processes that have been “suspended”, after the completion of normal us.
    Can be useful on the server, the work of many users. The script is optimized in order to minimize itself burdened processor.

    Thank you for the opportunity to share this.

    Copy the following text from “@echo off” and save it as a Batch file (extension .BAT) with any filename that You want.
