Exchange 2013. Got error 500 when try to login to ECP.

Problem: when trying to access exchange control panel, after entering credentials server returns error 500. If you look to event viewer you find the errors like this:

System.InvalidOperationException: Cannot load Counter Name data because an invalid index 'W3SVC_W3WP' was read from the registry.

Login to OWA is working normally.

Solution: On server run command prompt with administrative privilegies and run command:

lodctr /R

If you get an error, try to run again. After it finished with success,  restart IIS with command

iisrestart

After that try to login to ECP.
