I want set Notepad++ as the default editor. I tried to set it by right-clicking on a file, then Open With. But I did not see Notepad++ in the resulting list (even after clicking on Choose Other Programs).

When I try to redirect to Notepad++ through the Browse option to notepad++.exe file it is doing nothing. (Its not recognizing somehow)

  1. Start Notepad++ with elevated privileges.

    enter image description here

  2. In Notepad++, go to Settings, Preferences...

  3. Go to the File Association tab.

  4. Select fortran,TeX,SQL and then .sql and add it to the registered extensions:

  5. Click Close.

This answer is especially helpful for Windows 7. –  A. R. Diederich Mar 27 '13 at 3:16

The key here is that Notepad++ must be run as administrator (elevated privileges), otherwise the file association's will not "stick". –  Metro Smurf Jan 26 at 16:16

Start notepad++ as administrator, by right-clicking it's icon and selecting the relevant action:

enter image description here

In Settings > Preferences..., you can associate the extensions you want with Notepad++, using this dialog:

notepad++ association dialog

In this case, clicking on the red-outlined arrow would assicoate all .txt with Notepad++.

Don't you have to start notepad++ as administrator? –  Nifle Sep 14 '12 at 11:35

As an alternative, you can also replace notepad.exe with notepad++.exe (or notepad2.exe or another editor).

Take a look at this gist to get an idea on how to do it: https://gist.github.com/amarraja/3938304

I don't understand the upvotes and the selection of the right answer. None of these answers are answering the question, they just add extensions to be opened with Notepad++ but the question is "How do I set Notepad++ as the default editor?".

My answer is: modifying the registry. From this website, I found a pretty thorough regedit modification that works fine for me and really changes the default right click "Edit" program.

The hex portions are just the same path string to Notepad++, I don't know why those are in hex, but it is harmless. Copy the following text and paste it in a new .txt, save it, then rename it to filename.reg. And then just double-click it and accept the pop ups that warn you about modifying the registry:

I also wanted a solution without using notepad++ but rather Windows, since I know its a problem with the registry. I need this option for all files (not just SQL etc). So I agree that the upvoted solutions are not the right ones. I verified that the hex is actually just "notepad++". Haven't tested by applying the patch though. –  Jus12 Aug 1 at 10:25

The most direct route I've found is tell Windows to use Notepad++ (or Notepad2 or...) instead of the system default Notepad.exe by leveraging Image File Execution. It's safer (and easier!) than replacing system files or messing about with multiple registry entries.

Please follow the below steps:

  1. Right click on any text file.
  2. Select Open with...
  3. If Notepad++ doesn't show up in Recommended Programs or Other Programs you'll have to click on the Browse... button and copy the path of Notepad++.exe (usually C:\Program Files (x86)\Notepad++).
  4. Select Notepad++.exe
  5. Select Open and click OK.

Hope this is the easiest solution of all :)

This is not an answer to the original question - the OP tried exactly this as documented in his question and said it didn't work –  DavidPostill Sep 16 at 6:39
