SPEED UP UR ACROBAT READER (ALMOST LIKE NOTEPAD)
Do u get irritated when acrobat reader takes 5/10 seconds to load when you want to open a pdf document. There is a way to speed up the loading.      
       1. Go to the installation folder of 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 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).
