Hi,
I tried registry edits from the Reddit post, but they didn't fix the problem. As for the other two links, it looks like those commands would reinstall ALL Microsoft apps/features which is not an option (Microsoft has lost the trust of privacy conscious users with its built-in spyware).
Looking at the defaults settings, I see an "XBOX-TCUI" link type, but there is no apparent way to set this to do nothing. If I click it, I only have the option to set it to the already default app "Xbox Game UI". How can I get this link to do nothing?
Also, I haven't "hacked" out any features. I simply used the package manager that is built into Windows to remove unnecessary and privacy infringing features. If the package manager has failed to correctly remove components and left behind broken bits of these components; that is a bug, wouldn't you agree?
