批處理根據注冊表判斷系統版本號

[已解決]批處理根據注冊表判斷系統版本號寫了一個讀取注冊表項，判斷系統版本號的批處理，win7下測試：假如沒有HKEY_LOCAL_MACHINESYSTEMSetupService Reporting APIComponentsCoreOS，Version值，以下腳本得到的結果是：

C: │本地系統│Windows 7 Ultimate│x64│(.7601)
nclick="copycode($('code0'));">復制代碼

，而我想要的結果是：

C: │本地系統│Windows 7 Ultimate│x64│(6.1.7601)
nclick="copycode($('code1'));">復制代碼

，以下腳本不知錯在哪里了，請各位高手指導一下，謝謝了！

自己解決了，分享給大家，謝謝大伙的幫助
