CU9 disables connection to Exchange 2013

In stage 14 cumulative update 9 throws this error twice:

Error:

The following error was generated when "$error.Clear();

       remove-PerfCounters -DefinitionFileName MailboxTransportSubmissionServicePerfCounters.xml

       new-PerfCounters -DefinitionFileName MailboxTransportSubmissionServicePerfCounters.xml

         " was run: "System.ComponentModel.Win32Exception (0x80004005): The configuration registry key is invalid

  at Microsoft.Exchange.Configuration.Tasks.Task.ThrowError(Exception exception, ErrorCategory errorCategory, Object target, String helpUrl)

  at Microsoft.Exchange.Management.Tasks.ManagePerfCounters.DeletePerfCounterCategory()

  at Microsoft.Exchange.Configuration.Tasks.Task.<ProcessRecord>b__b()

  at Microsoft.Exchange.Configuration.Tasks.Task.InvokeRetryableFunc(String funcName, Action func, Boolean terminatePipelineIfFailed)".

Now it is no longer possible to connect to the server from outlook. How to debug this?
