This thread has become a bit confusing because of contradicting answers (it took me quite some time to figure out which was the right solution) so I thought it might be a good idea to summarize the results from afrazier's and Justin Roettger's posts combinded with my own experiences:

1. Start regedit as administrator


2. Open HKEY_CLASSES_ROOT7-Zip.7z
   


3. Under that key, expand the Shell sub-key


4. Set the (Default) value to the string extract
   


5. Create a new sub-key named extract
   


6. Set the (Default) value for the extract key to Extract to
Folder
   


7. Create a new sub-key under extract named command
   


8. Set the (Default) value of the command key to:

C:Program Files7-Zip7zG.exe x "%1" -o*

(you might have to adjust this to match the path of your 7-Zip installation)

Instead of 7z with -aou like Justin Roettger suggested I ended up using 7zG, because this way you can choose to overwrite if you like just like extracting with the normal context menu.

That's it! 7z files are now extracted to a folder with their own name by double click. For other extensions like .rar and .zip you need to repeat these steps for the according keys.
(i.e. HKEY_CLASSES_ROOT7-Zip.rar and HKEY_CLASSES_ROOT7-Zip.zip and so on)

Oh and to clarify: It does work with multiple files selected as well. No batch file need.

The easy way

Install ExtractNow. You can configure it to do exactly what you want.

The hard way

Manual registry modification as follows...

• Start regedit as administrator




• Open HKCR.7z and look at the (Default) value. Take note of what that is (in my case, as a PowerArchiver user, it's PASZIP)




• Go to the registry key in HKCR named that. (in my case HKCRPASZIP)




• Under that key, expand the Shell sub-key




• Set the (Default) value to the string extract




• Create a new sub-key named extract




• Set the (Default) value for the extract key to Extract to Folder




• Create a new sub-key under extract named command



• 
  

  Set the (Default) value of the command key to

  
  
  

  C:Program Files7-Zip7zG.exe x "%1" -o* -aou
  
  

  
  
  

  (you might have to adjust the path)

  
  

Thanks to Justin Roettger for pointing out the correct name variable needed for this.

That should be it. Now 7z files are extracted to a folder with their own name by double click. For other extensions like .rar and .zip you need to repeat this steps for the according keys.

If you only want to make the changes on your user account instead of system-wide, modify HKCUSoftwareClasses instead of HKCR. HKCR is a virtual key that's a union of HKLMSoftwareClasses and HKCUSoftwareClasses where the data in your account (HKCU) overrides the system-wide data (HKLM). Normally running regedit as an Administrator means that modifying HKCR alters system-wide data in HKLM.

Extracting multiple files

Of course, this won't work if you have multiple files selected. If you want that to work, you need to create the following batch file:

@echo off

:top

if "%1"=="" goto :EOF

7z.exe x "%1" -o"%~dpn1"

shift

goto top

Now, follow the instructions above. In the very last step, set the (Default) value of the command key to C:PathToFile.bat %*

All of the registry modifications are untested from memory, but should be correct.

Here's PowerShell script I wrote based on @haiggoh's answer. Before you run it, you need to open 7-zip, go to Tools->Options and associate 7-zip with wanted file extensions. After that, run the following PowerShell script (with admin rights):

$7zInstallationFolder = 'C:Program Files7-Zip'

$reg = [Microsoft.Win32.RegistryKey]::OpenBaseKey([Microsoft.Win32.RegistryHive]::ClassesRoot, [Microsoft.Win32.RegistryView]::Default)

$subKeys = $reg.GetSubKeyNames() | where { $_ -match '7-Zip.' }

foreach ($keyName in $subKeys) {

    $key = $reg.OpenSubKey($keyName + 'shellopencommand', $true)

    $key.SetValue('', '"' + $7zInstallationFolder + '7zG.exe" x "%1" -o*')

}

Of course, make sure that $7zInstallationFolder variable contains correct path to your 7-zip installation.

Pass parameters like this:

7z x "%1" -o"%1.d"

I recall hearing complaints about Windows 7 not allowing to directly edit file actions. I don't know if this is true or not... but if it is, save the following as a *.reg file and import it.

Windows Registry Editor Version 5.00



[HKEY_CURRENT_USERSoftwareClasses7-Zip.7zshellextract]

@="Extract to folder"



[HKEY_CURRENT_USERSoftwareClasses7-Zip.7zshellextractcommand]

@="7z.exe x "%1" -o"%1.d""

Here is a .reg file that configures Extract to folder as the default behavior when double-clicking files with one of the following extensions - 7z/CAB/GZ/GZIP/RAR/TAR/ZIP. You could do it for other file extensions using the same approach. I prefer the Windows default behavior for ISO/VHD mounting, so I didn't change that, and 7-Zip supports many other file types that I don't commonly encounter so I didn't change it for those.

You can revert this by going into 7-Zip File Manager, Tools, Options, and change the file associations as desired.

I tested on Windows 10 x64/7-Zip 15.12 x64. Because it uses C:Program Files for the path to 7-Zip, you definitely need x64 Windows + x64 7-Zip, but I only tested on Windows 10.

You will have the same right-click options as before, this only changes what happens when you double-click, and only for those seven file types (again, you could do this for other file types using the same approach).

If there is already a folder of that name, it will give you the same 7-Zip prompt you get normally, with options for Yes/Yes to All/Auto Rename/No/No to All.
