If you are one of those frustrated with the long long time taken by the Acrobat Reader to load, then use following trick.
Download Adobe Reader SpeedUp from Softpedia, install it and you are through.
It actually speeds up Adobe Reader's launch time by disabling the majority of plugins that are completely useless for most users. It's completely free from any malicious scripts.
Or, alternatively, if you don't want to use any third party program on your machine, follow these steps.
1. Go to the installation folder of acrobat reader (eg. C:\program files\adobe\acrobat\reader\.. ).
2. Move all the files and folders from the “plugins” directory to the “Optional” directory.
It will prevent Acrobat Reader to open the (mostly) useless plugins and load the Reader faster.
