In Adobe Acrobat Reader 11 XI, you can remove the annoying "Tools" and "Fill & Sign", that appear on the top right corner.
1. If open, close Acrobat Reader.
2. Go to C:\Program Files (x86)\Adobe\Reader\Reader\Services.
3. Rename DEXEchoSign.spi to DEXEchoSign.spi.BAK.
Rename DEXShare.spi to DEXShare.spi.BAK.
That's it.
