Always asked for admin yes or no to start launcher. Well, if you click more details, and then options to change when it asks for the admin (because I was curious), this, too, caused my launcher to revert. After having to restart to even get launcher running, it's now downloading again. This time total files are 81k instead of 93k when first installed.
I know they have a post in news section about never hitting the "no" option as asked. But, I didn't expect even looking at options would cause this. This post is mainly a reminder to all to always pay attention when starting launcher. Yes, I made a mistake by not just hitting "yes" as usual but throw me in the list of frustrated players.
If there is one good thing from my experience so far, it's that I didn't have to do anything through the microsoft store again.
I'll edit if if I run into more problems.
