Hi rediska,

I will tell you all controls that DNN use for login and user registration. Check these paths and try to translate all controls.
..admin\Authentication\App_LocalResources
..admin\Users\App_LocalResources
..\controls\App_LocalResources

Let me know if you couldn't translate a specific label or field.

I hope it will help!
Make it Accepted Answer if it's right solution.

Hi rediska,

If localization problem is occour only with "Preferred User Information".
...\App_GlobalResources\SharedResources.resx   
<value>Preferred User Information</value>

Maybe it will help,
