I'm trying to hijack notepad with the hack described at

I created a registry file to do this, but it won't work. The confusing thing is that regedit reports a successful merge. It did indeed create the key, but it will not create the value (Win7 ultimate 32-bit).

Here's the relevant code:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\notepad.exe]
"Debugger"="\"C:\\Program Files\\_doc-related\\AkelPad\\AkelPad.exe" /z"

I've also fiddled around with the quotation marks (reducing them to one set and taking away the double backslashes, etc.), like so...

"Debugger"="C:\Program Files\_doc-related\AkelPad\AkelPad.exe" /z

...and still get the same result. Anybody know what's going on? Of course I could just do this manually in regedit (at least I assume so--haven't tried, stubbornly holding out for a working regfile), but I want to find out what's going on because I need to know whether there are some "protected" items that simply can't be done by regfile. Although I would expect such keys to report that they can't be changed, as do other system-protected keys, rather than generating the kind of false positive I'm getting.

If you want a working REG file or want to see what mistake you're making, the easiest way is to open regedit, add the value, export to a REG file and compare with your non-working version. – Karan Mar 3 '13 at 23:38

I'm not sure what's going on for you trying to merge, but you can try the reg command instead:

  • Open a command-line as Administrator.
  • Type/paste:

    reg add "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\notepad.exe" /v Debugger /t REG_SZ /d "\"C:\Program Files_doc-related\AkelPad\AkelPad.exe\" /z"

  • Hit Enter. :)
