FIX

 

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

322756  (http://support.microsoft.com/kb/322756/ ) How to back up and restore the registry in Windows


To prevent the entries from being logged, use either of the following methods:

Method 1

Enable the Disk Performance Counters: Run the diskperf -y command from a command prompt, and then press ENTER.

Method 2

Prevent the performance library from checking the disk counters by modifying a certain registry key value. You can set this value programmatically through your performance data collection program or statically through by using Regedit or Regedt32. If you set this value statically in the registry, information from the counters will not be available unless you change the key value to 0 or delete the key.

To set the key:

  1. Click Start, click Run, type regedit, and then click OK.
  2. Locate and click the following registry key:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PerfDisk\Performance
  3. Create a new registry DWORD value: On the Edit menu, click New, and then click DWORD.
  4. Type Disable Performance Counters in the Name box.
  5. Right-click the Value icon, click Modify, and then type 1 in the value Data box.
  6. Quit Registry Editor.
