It depends on the Internet Explorer version. If you're using IE8 and down then the easiest way is to download a csv file one time and then uncheck the 'Always ask before...' checkbox. For IE9 and up, you should:

  1. Launch Registry Editor (Start >> Run >> regedit.exe)
  2. Expand HKEY_CURRENT_USER
  3. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell
  4. If it doesn’t exist, create the AttachmentExecute key
  5. Create the {0002DF01-0000-0000-C000-000000000046} key
  6. Create a new Binary Value with the Name Excel.CSV*
  7. Re-launch IE and test – should be now working ok

*In order to know the name of the binary value you should run at command prompt the command assoc.csv, in my case it was Excel.CSV

I got to this answer from several places, mostly from here, but if it still doesn't work I'd try this thread.

I recently (4-Nov-2015) found that other Group Policies (I don't know which ones; but my project had two different enterprise groups stop auto launching) will disable the auto launch even if the {0002DF01-0000-0000-C000-000000000046}\ registry entry is in place. To once again regain the auto launch behavior, you have to White-List the application as well. To do this:

- Create a new Binary Value with the Name: Application\<executable_name.exe>

To continue the above example, you would add the executable for Excel or Application\excel.exe as a new Binary value.

NOTE: Application is not a key. It is simply part of the name.

I wish I could point to research or documentation on this. This solution was only found by using Microsoft's Process Monitor (procmon) and noticing that the Application\<executable_name.exe> name was queried in close proximity to the {0002DF01-0000-0000-C000-000000000046} query. Even after I found the Application White-List element, I still could not find a reference. If someone can find an actual reference, please add it to one of these answers.
