Windows 10: Licenses registered to username should be recoverable after thefts have occurred?

I'm looking to recover my windows licesnces since some where purchased and not digital OEM. Regardless I am unable to recover my windows Enterprise 10 education although my devices are still listed as my own. I can't seem to find the slightest way to even use the bitlocker kyes. I really find this very absurd and the little technical support is not valid on specifics. I wouldn't mind if someone who has experience the same would reply. I have given up on trying to reach Microsoft and also locating software and certifications as well as licenses. it's hard to recover from identity theft and prop

Username or Password not registering on certain site

Windows 10. When I log onto a certain school email account, from any browser, and put in my username and password, it says 'invalid'. Yet on a smartphone it works as usual! The email site says nothing changed with them, and all other email usernames
and passwords work ok on all other sites. It's as if the site isn't registering my info, but only from my computer, and again, from any browser. Any suggestions?

 

Username registered

When I registered my phone 18 months ago. A username came up not of my decision. It repeated my name. I have tried several times to put in a password but nothing works. This means I am unable to get any apps.

how can I change the username and password.

or reset it and keep my stuff.
