Get disk perfmon failed Error

CCBoot Server uses WMI to retrieve disk performance data. The error Get disk perfmon failed! Code[7] occurs when this query fails due to a COM security initialization conflict (RPC_E_TOO_LATE).

1. Open power shell as Administrator and write “Get-Service wmiApSrv | Select-Object Name, Status, StartType”. (Figure 1)

Figure 1

2. If status is not running, then type “Set-Service -Name wmiApSrv -StartupType Automatic” then “Start-Service wmiApSrv”. (Figure 2)

3. On Windows Server 2026, open Terminal as Administrator and run the following commands one by one:
   cd C:\Windows\System32
   lodctr /R
   lodctr /Q
   winmgmt /resyncperf
   wmiadap /f
   regsvr32 wmiaprpl.dll
   net stop winmgmt
   net start winmgmt

4. Verify the Fix
   Run the following command to check if disk performance counters are working:
   Get-CimInstance -ClassName Win32_PerfRawData_PerfDisk_PhysicalDisk

5. After that, the issue should be fixed. The newer version of CCboot server will not have this issue and service will be started automatically.
