Set default SIP
The default SIP on practically every device is the Keyboard. You may prefer entry with a different SIP. If so, you can set this to be the default SIP through:
HKCU\ControlPanel\SIP\DefaultIM = |SIP ClassID|
The |SIP ClassID| will depend on the SIP's ClassID, which may vary per-device. You can find the correct ClassID by searching for "IsSIPInputMethod" in HKCR, then going to the top key and checking the name of the SIP that's in the (Default) value.
Please note that this doesn't work with all SIPs. Transcriber/Calligrapher are two examples of this.
You can, however, set Transcriber as the default SIP by starting Transcriber.exe on startup. (This should be moved to, or added to, non-registry Tweaks page)
WARNING: Do not assume that the below ClassIDs would be -as found- on your device! Setting it to a non-existant SIP may prevent your device from booting up!
Howevere, when I did a soft reset, the screen turned white which means that the settings did not work and I hard to hard reset. Is there any other way to get Phone Pad to be the default SIP.
