Windows 10: Unable to Login to Domain

I encountered the same problems with 2 of 4 new HP 15-au060UT laptops we added to our domain.

They came pre-installed with windows 10 Home so I did an upgrade to windows 10 Pro, and joined our local domain.

This worked fine and i could log into my user account on 2 of them with the following logon method (DOMAIN\USERNAME)
But the other two kept coming up the the same error Incorrect username/Password.

The way i got into the other two was by entering username@domain instead of using domain\username
See Active Directory for correct username@domain credentials

 

Here is a fix that will save you a reinstall and a 500$ call to Microsoft.

1) Boot into recovery by holding shift and hitting the powerbutton at the login screen and while holding shift click restart make sure you know a local administration password if not boot from a windows 10 install disk and click repair.
2) Select troubleshoot > advanced options
3) Open Command prompt
4) type Regedit
5) Select HKLM
6) Click File at the top and select load hive
7) Browse to C:\windows\system32\config and select SYSTEM, Click open
8) Give the hive a name any name i suggest Loaded Hive
9) Then expand HKLM if not already and expand the hive we just named and loaded
10) Expand controlset001 > Control > ProductOptions
11) Edit the key "ProductSuite" and delete the "personal" line then click ok if it error that ok its just cleaning up the format of the key if you click ok on the error you should still see that personal is now gone.
12) Reboot and try to sign into your domain again.






*Notes*
Its important to brows to C: because if you dont know already the recovery has its own storage area and registry so we want to make sure we effect the correct registry.

 

Thanks for that, Bobo! Always good to see another tech willing to give specific advice like that.

Deleting this registry key didnt fix my issue, however. How did you figure this out? Maybe another Key is the real culprit here.
