Umm, first off:
$ cat /proc/registry/HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/sshd/Parameters/AppArgs
(which indicates the absense of the newline in that value), so you have to
at least use "echo -n".
$ 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"
