Hi Justinder,

Thank you for posting your query in Microsoft Community.

Occasionally, Windows might not read your user profile correctly, such as if your antivirus software is scanning your computer while you try to log on.

Hope this helps, Good luck :)

*EDIT*

Scratch my post below - I missed a step in Kapil's advice involving copying the NTUSER.DAT file. I managed to copy one from the administrator account into "Default" and it let me log in.

Thanks for the help! I'm a happy man now :)

**END-EDIT**

Just to bump this really. I too am having this problem. I have a domain set up with currently 2 PCs connected.

On one PC, I can log in no problem on two accounts.

On my other PC (my main one), I cannot log in with my colleagues account, it comes up with this error. 

I have tried numerous steps (both from Microsoft and other google searches), including the above, and nothing seems to work.

Please help.

John.

I have HAD ENOUGH OF TRYING TO FIX THIS PROBLEM!!!

Apple, YES MAC, can I add multiple users without having to poke through registries?

Microsoft don't know how to create simple computer users.... they have method1, 2, and 3... as per here https://support.microsoft.com/en-us/kb/947215 that still don't work!!! All after hitting create...

There is even a method for deleting and creating new defaults.... in C:\users....

I have no idea how to resolve this but now W10 has taken 3 days of my time, wasted... no resolve... Thank goodness it's free*, it is not worth paying for!

Come on China give us a decent operating system not like this Made in India!

Can you provide a link that will solve these w10 ills?
