User profile service failed to sign in

Logon to windows(in my case win8.1) failed with error "user profile service failed to sign in", "user profile cannot be loaded". I was able to create user, but it was impossible to login with that user. Users with already created profiles can login without any problem.
After browsing internet for one day no solution was found. I check system integrity (sfc /scannow), check disk for errors (chkdsk), made restore of system files (dism utility), check registry and etc. All was unsuccessful. The problem was that something was wrong with default profile permissions. To fix this issue go to c:\Users\Default right click on that folder, select "properties"->"security"->"advanced"->"change permissions"->select checkbox "replace all child object permission entries from this object"  and click "OK"

Then try to login.
