The major reason people avoid it and install third party software is its slow start up time. Use this tweak to open any pdf file in Acrobat reader very fast. With our method, you can speed up your Acrobat reader up to 10x times faster.

1. Go to the installation folder of Acrobat Reader.
For 32 bit version, go to:
---
1 2 |
C:program filesAdobeReader X.0plug_ins # (Where, X.0=Version of Adobe Reader) |
For 64 bit version, go to:
1 2 |
C:program files(x86)AdobeReader X.0plug_ins # (Where, X.0=Version of Adobe Reader) |
This ScreenShot shows the method in 64 bit version in two steps:
2. Move all the files and folders from the “plugins” directory to the “Optional” directory.
For 32 bit version, go to:
1 2 |
C:program filesAdobeReader X.0optional # (Where, X.0=Version of Adobe Reader) |
For 64 bit version, go to:
1 2 |
C:program files(x86)AdobeReader X.0optional # (Where, X.0=Version of Adobe Reader) |
(we repeat.. cut and paste the files NOT copy & paste; press [ctrl]+[A] to select all, [ctrl]+[X] to cut and [ctrl]+[V] to paste). It may give security prompt, accept it:

Also make sure that acrobat reader is not open else it will lock the files and not allow you to move the files).
When you first run Acrobat after doing this tweak, it will bring up installation window to rearrange some system information, Acrobat Reader will not open this time. After the first run, it will never behave like this.
Now your acrobat reader will load very fast and almost as good as notepad.

Note: A reported bug of this method by a regular user of our old website (CustomizeWindows.co.nr):
Mr. Nikhil from India reported on 8th of Aug, 2010; that the embedded pdf file in websites, which needs to be opened within the browser (Internet Explorer and Google Chrome to be specific) does not load correctly, in case you adopt this method. Offline pdf files/downloaded pdf files however, have no problem; as usually.

There is no ‘Optional’ folder. Maybe a different folder for Windows 7?
There is no ‘Optional’ folder. Maybe this folder not in Windows 7?
Create that folder named Optional. Then do the rest.
Acrobat X shows install bar and then appcrash. Every time I try to open. Any suggestions?
SO Windows 7.
