    Windows won't display my user name instead on the Start Menu and Log In screen it just shows my Microsoft Account email and again below. I've had this issue since the Insiders Preview started and made posts in the Feedback App as well. Now signing out of the MS Account and back in will resolve the issue, but as soon as I restart the PC for any reason it just defaults back to the MS Account email. Is anyone else experiencing this issue?

    I'm having the exact same issue. I thought it was a holdover from upgrading my one machine to the insider builds and keep hoping with every update that it gets fixed. But yesterday i upgraded my SP3 to the final release, with no insider builds or connection involved at all and it shows me the EXACT same issue.

    I've posted in the feedback about it and searched everywhere to see if there are any issues or resolutions for this. Only thing that works as you've mentioned is to switch to a local account, and then switch back to my MS account. But thats only temporary. It doesn't seem to break on every reboot though, only certain update reboots, so its not always 100% replicable.

    My older test machine though (which I upgraded from Win 7 using insider builds) has never had this issue, and the only reason i can think of is that it wasn't using a Microsoft account sign in before the upgrade. Both my main laptop and SP3 which have the issue upgraded from win 8.1 where i was signed in with my Microsoft account. Could this perhaps be related. I keep threatening to do a full clean install or a "reset" but I need to work up the energy to actually spend a day reinstalling everything else once i do.

    Have you perhaps managed to find a solution or found anything that helps?

    Anyone else out there having this issue! MS help!

    you could just upgrade your 10074 install to 10240 with the ISO. That should work. :)

    I guess I found out something:
    The problem affected my laptop which had been upgraded to Windows 10 Pro from Windows 8.1 Pro.
    I installed Windows using a MS account, and then joined my Homegroup.
    Then the problem appeared: user name is gone, email address appears twice at logon screen.
    After several trials I disconnected all the computers from the Homegroup, which was created in a Windows 8.1 Pro desktop, and then I created a new Homegroup from the Windows 10 Pro laptop.

    My Windows 8,1 desktop and my also Windows 8.1 HTPC joined the new Homegroup flawlessly.

    Evidently there is an issue regarding MS accounts when a Windows 10 PC joins a Homegroup started in a Windows 8.1 machine.

    Hope this info is useful.

    My Windows 10 laptop has not changed my full name by my email so far.

    Thanks Mirko!

    Awesome, that would so explain why my one win10 machine isn't showing this issue (its not part of the HomeGroup!). I'v been trying all afternoon to actually get the HomeGroup to disappear from my network. For some reason all my win10 machines just say "Available to Join". So trying of figure out which of my machines is keeping the HomeGroup alive (I do still have some machines running win 8.1, so wonder if they're to blame for this).

    Anyone else managed to solve this issue using Mirko's discovery? :)

    Sorry to bring bad news but the isuue reapeared.
    I upgraded the HTPC and after it joined the Homegroup the problem reappeared: display name is gone and email address is shown twice at logon.
    There seems to be an issue in Windows 10 when you join Homegroups using ms account based users.
    Regarding your issue, unjoin all your machines from the homegroup, tthen they shouldd be ready o create a new homegroup.

    If they say that they have been invited to join to a group, uninstall the NAC of the machine where the homegroup was creadted and then reinstall it.
    Now the homegroup should be gone.

    This can also be done by deleting all files and folders located at a users/username/appdatasomething.... but it is faster the previous way.

    By this means the phntom homegroup is gone.

    I`ll keep looking for a fix of the gone duplicate mail address at logon.

    Mirko: I feared as much since the problem occurred again for me while after I left the homegroup and before I even tried to create a new one (I have managed to create a win10 based homegroup now). Seems my login screen is still displaying correctly (for now), but start menu and account settings screen have lost my name again. Its super perplexing. Am hoping to try get some insight from the Answer Techs.

    It seems there definitely are other people having this issue. I found a Microsoft Answers Community page with the same issue, not sure if you guys want to go and add your input there so we can get this up the food chain?

    After several tests and an unsuccessful talk with an MS support guy I think I'm reaching an explanation.
    I created a new Microsoft account , then I switched all my computers to local accounts and took them out of the previous homegroup.
    Then I started to switch them to the newly created MS account.
    Then I created a new Homegroup.
    Then I joined all the computers to the new Homegroup.

    After one day of closing sessions, cold and hot reboots and even a router reboot the double email at login issue seems to have disappeared.

    What made me think of doing this is that the previous MS account that I was employing to install Win 10 had a gmail address as an alias.
    I also had a MS account with a gmail address as primary alias. It seems that if two MS Accounts have crossed alias and the same username, something goes wrong with the Window s10 user profile.

    So far the problem is gone.

    Hope this info its useful.

    Glad you managed to get it resolved, but for most of us I just don't see that as a viable solution. My MS Account is tied to an outlook.com address, and I have a host of services attached to that address as well: Office 365, Xbox Live Gold etc. I just wish we could find out if MS is aware of this issue and if they are actually trying to do something to solve it. Suggesting I create a completely new MS Account just isn't feasible. Plus this issue is occurring for me on 3 separate machines with vastly different configurations (including my SP3). Something must be causing the issue though, because it is fixed momentarily when you switch to local and then back to MS account, so its definitely getting the data. Short of switching to local, creating a second local account and then tieing that into my MS account to see if it still occurs, I'm not sure what else to do... I really hope MS can advise on this. The support guy I chatted to was baffled and spent about an hour remotely controlling my machine and trying all the things i'd already tried, so their support techs aren't even aware of this bug.

    Here's hoping a fix is in the works!

    Is your MS account linked (by an email allas) to gmail account?
    08-14-2015 01:06 PM
  13. halcyonboy's Avatar
    Nope. The only thing alias wise may be that the original address was an @live.com address, so the outlook.com is an alias that I switched to be the primary alias. But still, that's all in-house MS stuff, really should not be causing these kinds of issues.

    What I will possibly try is create a new local account with admin rights, and then after switching my main account to a local again, switch that new one to my ms account. perhaps there is something hanging around from the windows 8.1 user account that is causing this? Still irritating though.

    In my case the MS account that had the problem initially was based on a gmail account, which then I switched to an outlook.com.ar address.

    I think I have discovered a possible reason this is happening. So I tried creating a second local account, and then switched that to my MS account. One reboot and the issue showed up on the new account.

    Based on what you said about aliases it got me thinking, my @outlook.com account started off as a @live.com account, I created the outlook.com alias and then changed that to my primary alias when that feature was enabled. Never had any issues with it before. So what I did was I changed my primary alias back to the @live.com account. Then I switched my sign in back to a local account (the original account, the newer one I removed completely), and then switched it back to MS account, but this time signing in with my @live.com address (the current primary alias).

    After two reboots and signing in and out there was no issue at all. The problem seemed fix. I left it for about an hour or two and it was still working properly. I then went in and switched the configuration on the server back to having the @outlook.com address as my primary alias (to test and see if it was such a coincidence). I then left everything as it was on my machine. Didn't change anything locally, but waited for the primary alias to sync to the machine. Within half an hour I noticed the alias had synced and boom issue was back. So it seems to explicitly be tied to the primary alias being different to the original account email address. This would also account for why your Gmail alias was causing issues if I understood you correctly.

    do any of the rest of you having this issue make use of a different email alias? At least this way we can get MS to look into it, also why most pp. aren't reporting the issue then too...

    I think somebody found a good clue!

    Mirko, Thanks your insight about the former account alias got me to a fix. I searched the registry on my laptop (displays two email addresses) and desktop (displays name and email correctly) for mentions of my *** Email address is removed for privacy *** and found one that existed on the laptop but not the desktop. So I deleted it and rebooted. Problem solved and it worked on both of my laptops that were displaying it incorrectly.
    The reg key in question is:
    HKEY_USERS\.DEFAULT Software Microsoft IdentityCRL StoredIdentities OldAliasedAccount at hotmail.com
    Deleting that key and leaving the one for the CurrentAccount at outlook.com fixed it on both machines. So far I have not seen any adverse impact.
    Thanks again for your assistance.
    Anyone else using this fix, please be careful editing the registry.
