1. Go to the installation folder of acrobat reader, This should be

C:\program files\adobe\acrobat\reader\..   in most of the cases

2. Move all the files and folders from the “plugins” directory to the “Optional” directory. (make sure that  you cut and paste the files NOT copy & 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 as good as notepad.
