win xp不能進入安全模式的解決方法

問題提出：電腦軟硬件應用網電腦門診第2224號嘿嘿黑馬問：我開機按f8進不了安全模式，為何？

分析解決：無法進入安全模式一般為病毒或者其它軟件操作不當造成。一般情況為系統注冊表中safeboot項被修改造成的。

解決辦法一：將以下代碼復制到記事本，另存為xxx.reg的格式(如我另存為:safeboot_winxp.reg)，雙擊選擇“是”添加到注冊表重啟即可。

方法二：以上方法提示失敗的話（一般就是禁止了注冊表編輯），請按以下操作。進入正常模式，開始菜單－運行－輸入“gpedit.msc”點確定(輸入時請不要輸入引號)。打開“組策略”窗口後在“本地計算機策略”窗口中依次找到“用戶配置→管理模板→系統”，在右邊的設置窗口中雙擊－“阻止訪問注冊表編輯工具”，打開其屬性對話框，並在設置中點選“已禁用”，然後“應用”並“確定”；再次運行safeboot_winxp.reg（上文編輯的文件）即可。
