Acrobat Reader RdrCEF


Recommended Posts

Hi guys,


I noticed today that upon opening a pdf-doument (the very interesting read shared by Judith here) my computer was working quite much. When I looked into the process manager, I noticed that a new background process (RdrCEF.exe) is started along with the Acrobat reader that uses 30-45% of my CPU and 170-250 MB RAM! According to a quick google search it continuously sends data to Amazon. As many people on this forum are quite picky regarding internet security, I wanted to make you aware of this point and will search for another pdf-viewer myself today.


Best regards,



Edit: I just noticed that apparently this problem is acutally quite old (most things I found are from 2015), but it appeared just today for me, so either it is a problem solely for me or it is currently resurfacing, but I think it is stil worth checking.

Another vote for XChange; it has the best font rendering of the non-Adobe Windows PDF viewers I've tried. (Some of them can be startlingly bad with certain documents: my testbed is the manual from Arcanum: Of Steamworks and Magick Obscura.)

if you are on windows 10 pdf files get loaded into microsoft edge. completely avoids using the dodgy reader. although microsoft edge is rather dodgy but you dont get the adverts that you get if you use it as a web reader.

      Sometimes life throws a curveball - other times it straight up tries to take you outta the game. Been one thing after another lately but I ain't goin without a fight!

      My Uber rating (as a passenger) is 4.71. Is there still hope or should I just kill myself? What's yours?

      Did I mention how absolutely grateful I am that TDM didn't get (and can never be) assimilated by a huge company like Microsoft, as is what happened to Minecraft?
