I've resolved with the following steps:
PS C:Windowssystem32> cmd
Microsoft Windows [Version 6.2.9200]
(c) 2012 Microsoft Corporation. All rights reserved.
C:Windowssystem32>lodctr /R
Error: Unable to rebuild performance counter setting from system
backup store, error code is 2
C:Windowssystem32>cd ..
C:Windows>cd syswow64
C:WindowsSysWOW64>lodctr /R
Info: Successfully rebuilt performance counter setting from system backup store
C:WindowsSysWOW64>winmgmt.exe /RESYNCPERF
C:WindowsSysWOW64>
