Adobe Acrobat reader always consumes much memory when it is start. The reason behind is, its load all the plugins, even the plugins that you do not use. This tutorial removes all the plugins from the plugins directory to elsewhere. Hence, whenever you open Acrobat reader its directly open the files without loading any plugins and the speed is just like NotePad.
1. Go to the instalation folder of Adobe Acrobat reader
( C:\program files\adobe\acrobat\reader\..whatever )
2. Move all the files and folders from the " plugins " directory to the " Optional " directory. ( I repeat... cut and paste the file not copy and paste ).
also make sure that acrobat reader is not open else it will lock the files and not allow you to move the files ).
Now your Acrobat reader will load very fast and almost fast as NotePad.
