In fact even removing it does not seem to stop its semi zombie like behaviour. If you replace the built-in Default app with your own, any BSOD or even a restart can mean that the default app gets unpacked and re-installed to replace yours.
If you have no errors in use, the re-boot seems more reliable and the newly chosen app will more likely remain as the default.
In my case, the replacement happens some time after the re-boot (10-30 secs) and it may be due to the fact that I have removed the AllJoin stuff from my default app as well as the device.
