这个问题很奇怪，下了一个网络加速的reg文件，提示“指定文件不是注册表脚本，只能引入注册表文件。”这个文件系统格式化前可以导入，重装后不能导入了！我的系统关联文件正常，卡巴扫描没有病毒。但是另外有个reg文件又可以导入注册表。百思不得其解！下了几个修复工具，RegSupreme Pro。WinASO RegFix。sreng还是没有解决问题！我把2个文件用方本贴上来，大家帮我分析一下，谢谢了！
可以导入的reg文件：
REGEDIT4

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System]

"DisableTaskmgr"=dword:00000000

以前好多reg文件都不能用了，都是修复文件关联文件错误的！
请各位高手帮帮忙！谢谢了！
