窓使いの憂鬱で&ShellExecuteが遅い

&Sync &ShellExecute("open", "%SystemRoot%/explorer.exe", "/n,::{20D04FE0-3AEA-1069-A2D8-08002B30309D}", , ShowNormal)

&Sync &ShellExecute("open", "C:/WINDOWS/explorer.exe", "/n,::{20D04FE0-3AEA-1069-A2D8-08002B30309D}", , ShowNormal)

&Sync &ShellExecute("open", "C:\\WINDOWS\\explorer.exe", "/n,::{20D04FE0-3AEA-1069-A2D8-08002B30309D}", , ShowNormal)

この３つの表記で最後のが一番早かった。何故。
