You can use window's own commandline delete function (del for files and rmdir for folders/directory trees), which is faster than explorer's delete function, but it bypasses the trashcan entirely.
To avoid the need to enter cmd and typing/pasting paths everytime you want to delete something you can create a short bat script and add it to window's SendTo-menu.
Bat-script (save wherever you want, with .cmd or .bat extension):
IF [%1]== GOTO Continue
echo Deleting %1...
del /f/s/q %1 > nul
rmdir /s/q %1
Create a shortcut to the script in the following folder:
Now all you have to do is right click on file(s) or folder(s) and select "Send To" -> "youscript".
