If microsoft could just fix the damn "self-delete after every boot", we could find ways around it. But as it is, I highly doubt it. I'm just downloading the 11BG part of it and not launching it to see if that also "self-deletes". I'll commit no breathe if even that happens.
Edit: After shutting down my laptop, checking the Mutable/Oxyna file where the launcher is located, it seems like it is still intact. Double checking it, I also check the MutableBackup and didn't find any file in there. So the launcher doesn't commit no breathe.
Edit2: Being paranoid and testing only shutdown, I also tested for restart and lo and behold, the launcher is still intact. Still in Mutable/Oxyna and nothing in the MutableBackup.
And no, I did not try to execute the launcher in both tests. Try at your own risk cuz I'm waiting for a patch.
