Andy,

Since not all functions will clear the last-error code value on success, you need to check the return value from SHDeleteKey to know if an error occurred (a return value of 0 = ERROR_SUCCESS).

EAX = A1h

ERROR_BAD_PATHNAME
161 (0xA1)

i assume the key you are trying to delete is empty
at any rate - the error indicates that the key does not exist
check your strings   :U

another possibility - if you are running 64-bit OS
is that the key is virualized under wow64

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\TrayNotify]
"BalloonTip"=dword:00000005
"PastIconsStream"

Past_stream   db  "Software\Microsoft\Windows\CurrentVersion\Explorer\TrayNotify\PastIconsStream",0

I have a VB script that deletes the key and then it stops and restarts explorer.

Maybe that is the problem.

remove the first backslash from the paths and it should work!  They should be:

Icon_streams  db  "Software\Microsoft\Windows\CurrentVersion\Explorer\TrayNotify\IconStreams",0
Past_stream   db  "Software\Microsoft\Windows\CurrentVersion\Explorer\TrayNotify\PastIconsStream",0

Thanks, that was easy.
