Acrobat Reader ads
 

I am searching the net how to remove ads from acrobat reader and I found nothing. After some investigation I found that reader checks the folloing registry value to decide whether to show ads or not:

[HKEY_CURRENT_USER\Software\Adobe\Acrobat Reader\6.0\AdsInReader]
"bShowAds"=dword:00000000 ; 0 - do not show, 1 - show, default - 1

Preferences - Startup - uncheck "Show Messages and automatically update"

That's all :)

Maybe a little off-topic, but i recently found a small application which can remove the adds as well... however, that's only an additional function: it's main purpose is to speed up the loading of adobe reader, by loading only a few plugins...

it can be found here:
