How To PERMANENTLY TurnOff the Right Side Pane in Adobe Reader
To stop the"Tools|Comments" sidebar from automatically opening every time youopen a PDF so that you can READ your PDF in full screen, this solution workedfor me on both my desktop PC and laptop.
This is thesolution:
Go to C:\ProgramFiles (x86)\Adobe\Reader 11.0\Reader\Services (for win7 64-bit)
or
C:\ProgramFiles\Adobe\Reader 11.0\Reader\Services (for win7 32-bit)
Find and Deletethese 2 files: DEXShare.spi and DEXEchoSign.spi
Yes, you will stillsee the word "Tools| Comments" at the top but at least your PDFs willopen in full screen and you won't have to click "Tools" to hide thatstupid side pane every time you open a PDF.
