win7任务栏资源管理器无法打开怎么办

1、打开开始菜单，找到记事本的快捷方式，点击打开记事本

2、在记事本中输入如下内容：Windows Registry Editor Version 5.00[HKEY_CLASSES_RO晦倘佳鳎OT\CLSID\{20D04FE0-3AEA-1069-A2D8-08002B30309D}\shell\Manage]@=hex(2):40,00,25,00,73,00,79,00,73,00,74,00,65,00,6d,00,72,00,6f,00,6f,00,74,\ 00,25,00,5c,00,73,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,6d,00,\ 79,00,63,00,6f,00,6d,00,70,00,75,00,74,00,2e,00,64,00,6c,00,6c,00,2c,00,2d,\ 00,34,00,30,00,30,00,00,00"MUIVerb"=hex(2):40,00,25,00,73,00,79,00,73,00,74,00,65,00,6d,00,72,00,6f,00,\ 6f,00,74,00,25,00,5c,00,73,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,\ 00,6d,00,79,00,63,00,6f,00,6d,00,70,00,75,00,74,00,2e,00,64,00,6c,00,6c,00,\ 2c,00,2d,00,34,00,30,00,30,00,00,00"SuppressionPolicy"=dword:4000003c"HasLUAShield"=""[HKEY_CLASSES_ROOT\CLSID\{20D04FE0-3AEA-1069-A2D8-08002B30309D}\shell\Manage\command]@=hex(2):25,00,77,00,69,00,6e,00,64,00,69,00,72,00,25,00,5c,00,73,00,79,00,73,\ 00,74,00,65,00,6d,00,33,00,32,00,5c,00,6d,00,6d,00,63,00,2e,00,65,00,78,00,\ 65,00,20,00,2f,00,73,00,20,00,25,00,77,00,69,00,6e,00,64,00,69,00,72,00,25,\ 00,5c,00,73,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,63,00,6f,00,\ 6d,00,70,00,6d,00,67,00,6d,00,74,00,2e,00,6d,00,73,00,63,00,00,00

3、然后点击记事本工具栏的“文件”，选择“保存”

4、接下来，把保存好的记事本文件的后缀由原来的.txt改为注册表文件的.reg，重命名提示对话框中选择“是”

5、然后双击它，把这个改好的注册表文件添加进注册表，提示的话同样选择“是”，这样就完成了对任务管理器的修复
