Windows batch script to unzip files in a directory

Question

I want to unzip all files in a certain directory and preserve the folder names when unzipped.

The following batch script doesn't quite do the trick. It just throws a bunch of the files without putting them into a folder and doesn't even finish.

What's wrong here?

for /F %%I IN ('dir /b /s *.zip') DO (

    "C:\Program Files (x86)\7-Zip\7z.exe" x -y -o"%%~dpI" "%%I" 
)

Ansgar's response above was pretty much perfect for me but I also wanted to delete archives afterwards if extraction was successful. I found this and incorporated it into the above to give:

for /R "Destination_Folder" %%I in ("*.zip") do (
  "%ProgramFiles%\7-Zip\7z.exe" x -y -aos -o"%%~dpI" "%%~fI"
  "if errorlevel 1 goto :error"
    del "%%~fI"
  ":error"
)
