Windows 10: We couldn't sign you in to Xbox Live. - The system cannot find the file specified.

I have been struggling for MONTHS trying to sign into my Xbox App. I've tried resetting, uninstalling, Terminating, wsreset.exe, and I don't have app data under my users in my C: drive to wipe my data. I'm unable to play games with friends and play the games I've purchased. It is absolutely ridiculous that I find many threads with people who suffer the same issue with ZERO RESOLVE! Can anyone help me?

Xbox live sign-in fail

Hi,

An interruption with the Xbox Live server and failure to authenticate the Xbox login information are possible reasons as to why you're encountering this issue.
Kindly answer the following questions for us to advise the best approach in resolving this issue:

• Are you using the same Microsoft account to sign in to the Xbox app, the games, and the Windows 10 PC?
• Are you getting any error messages when signing in to your Xbox account and the games?

To determine if your Xbox profile is working properly, we suggest that you sign in to
Xbox.com. If you can sign in, that means your profile is all good. Otherwise, follow the on-screen prompts on how to update your account information.

 

Xbox 360 Live Update

A new update for the Xbox 360 has been released over Xbox Live. The update, available upon signing on to the Xbox Live service with a 360, offers a few minor bug fixes, as well as a seal over a minor security hole that would-be system hackers had been experimenting with. Here's the update list:

• Improvements to the Xbox Guide.
• Option to retain your saved games when you delete a profile.
• Increased accuracy of "last time played."
• Network configuration improvements for Xbox Live® members in the Netherlands.
• More detailed messaging for unreadable disk or region errors.
