    Metadata details:
    filename: disk_windows.go

    the code of the file until where you have to start completion: //go:build win
    
func init() {
	// enable disk performance counters on Windows Server editions (needs to run as admin)
	key, err := registry.OpenKey(registry.LOCAL_MACHINE, `SYSTEM\CurrentControlSet\Services\PartMgr`, registry.SET_VALUE)
	if err == nil {
		key.SetDWordValue("EnableCounterForIoctl", 1)
		key.Close()
