Adobe Reader is a very good software except the fact that it is extremely slow. Here are a simple but effective solution.
This trick will make Adobe Reader as fast as Notepad.
Note
This trick was tested using Adobe Reader 9.0 and it shall work on the older version as well.
First, you will have go to the installation folder of Acrobat Reader which default is at
(C:\Program Files\Adobe\Reader 9.0\Reader\)
Then move all the files and folders from the “plug_ins” directory to the “Optional” directory. (cut and paste the files and not copy and paste please take note). Also make sure that acrobat reader is not open else it will lock the files and not allow you to move the files.
The Reader may configure itself once again for the first time you open it. It will just restore the most important files back to “plug_ins” folder.
Now your acrobat reader will load very fast and almost as good as notepad.
