I just soft reset and it is indeed still working. This is what I THINK I did. I NEVER installed a disable SMS notification .cab, instead I made these edits:

HKLM\Drivers\BuiltIn\RIL : DisableSMSWakeUpEvent set to 1
HKLM\Software\Microsoft\Inbox : SMSNoSentMsg set to 1

Soft reset, didn't work.

Made this reg edit:
HKCU\ControlPanel\Notifications\Default : Options set to 0

Soft reset, didn't work.

Opened advanced config, set:
Messaging > SMS Sent notification > Enabled
Messaging > SMS Delivery notification > Enabled
Messaging > SMS Unicode support > Enabled

Soft reset, it worked! but I had a SMS delivery notification.

Opened up advanced config again, set:
Messaging > SMS Sent notification > Enabled
Messaging > SMS Delivery notification > Disabled
Messaging > SMS Unicode support > Enabled

Soft reset and viola.
