“Windows cannot load the user’s profile” – “Insufficient system resources”
Hope this may solve your problem.
Although the registry may have some part in you receiving this method I would try something different before you reconfigure the registry. If you have a network that you have multiple user accounts that log onto the same computer, then I would check the computer that you are logging into to see if there are old local profiles that could be existent. Old profiles could be corrupted and the new profile cannot be logged into.
To keep from getting this error, I would log into the computer as the Administrator, rename the old local profile, transfer any data out of the old profile to a new folder so data won't be lost, and then reboot the computer and try to log into the user account again. If this does not work, then you make need to make a new user profile and try that one.
As for the registry fix, you can go to Microsoft website listed below and they have an option that you can click to resolve the issue for you without you going into the registry:
