OK, so I missed to get rid of the output.
Another way would be to use the at-sign (@) in front of msiexec to 
suppress the output.

/passive and /qn are essentially the same.

'---code start (watch for line wraps)

<remove cmd="%ComSpec% /c for /L %N in (10,1,99) do @msiexec /passive /x {26A24AE4-039D-4CA4-87B4-2F832180%~NF0}">
      <exit code="1605" />

'---code end
