Umm, first off:

$ cat /proc/registry/HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/sshd/Parameters/AppArgs
-De $

(which indicates the absense of the newline in that value), so you have to
at least use "echo -n".

Secondly:

$ echo -n "-Der" > /proc/registry/HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/sshd/Parameters/AppArgs
bash: /proc/registry/HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/sshd/Parameters/AppArgs: Read only file system
$

AFAIR, /proc/registry has always been read-only.

What you *can* do, however, is:

$ regtool -- set /HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/sshd/Parameters/AppArgs "-Der"
$

HTH,
	Igor
