今天給一個客戶檢查服務器的時候，發現windows防火牆不能打開，顯示以下錯誤信息：
由於不可識別的問題 windows無法顯示windows防火牆設置
到網上找了找方法，電腦軟硬件應用網(http://www.45it.com.cn)告訴大家導入以下注冊表文件後重啟系統就會好的。
1. 將下列文本復制到“記事本”中，然後將文件另存為 Sharedaccess.reg：
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SharedAccess]

"NextInstance"=dword:00000001
2. 雙擊“Sharedaccess.reg”以將此文件的內容並入到注冊表中，並創建 Windows 防火牆注冊表項。
3. 重新啟動 Windows。
4. 單擊“開始”，單擊“運行”，鍵入 cmd，然後單擊“確定”。
5. 在命令提示符處，鍵入以下命令並按 Enter：
Netsh firewall reset
6. 單擊“開始”，單擊“運行”，鍵入 firewall.cpl，然後單擊“確定”。
一般情況下，導入注冊表重啟後就恢復了。以下是微軟官方的參考資料：
