Fixing Windows Performance Counter Errors

If Xackup reports an error related to Windows Performance Counters, this is usually caused by a corrupted counter cache — and it's typically easy to resolve.

Steps to Resolve

1. Click Start, type cmd, right-click cmd.exe, and select Run as administrator.
2. At the prompt, type the following command and press Enter:

   lodctr /r

Why This Happens

Windows stores a cache of performance counter data in the registry at:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Perflib\009

If this cache becomes corrupted (for example, containing blank entries), it can trigger performance counter errors. Running lodctr /r rebuilds the cache from the system's backup counter definitions, which resolves the issue.
