自从上次中了病毒IE，电脑一直有问题，
解决Windows7搜索功能不能用
。今天发现Win7强大的搜索功能不好用了。在网上google了好长时间，也没有找到解决办法。于是想到了上次除去病毒IE的办法，来修改注册表吧！下面说一下解决方案：
1、win键+r 打开运行窗口，输入regedit，
查看一下下面的位置，
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Desktop\NameSpace]，是否有下面三项：(此三项应该是关于Windows7 搜索相关的注册表项)
a.
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Desktop\NameSpace\{04731B67-D933-450a-90E6-4ACD2E9408FE}]
@="CLSID_SearchFolder"
b.
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Desktop\NameSpace\{4336a54d-038b-4685-ab02-99bb52d3fb8b}]
@="Public folder"
c.
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Desktop\NameSpace\{daf95313-e44d-46af-be1b-cbacea2c3065}]
@="CLSID_StartMenuProviderFolder"
如果都有的话，直接进入下面第2部分。如果没有的话，将上面的粘贴到一个文本中，并修改后缀名为reg，暂且命名为1.reg。然后双击导入即可。
注意文件的头要写上：
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Desktop\NameSpace]
2、进入[HKEY_CLASSES_ROOT\CLSID\，分别搜索04731B67-D933-450a-90E6-4ACD2E9408FE，4336a54d-038b-4685-ab02-99bb52d3fb8b和daf95313-e44d-46af-be1b-cbacea2c3065。三者都有问题。需要从正常win7系统中相应的注册表中导入相应的项。注意需要将原来有的删除，删除的过程可能需要权限，改为administrators权限即可。正确的注册表导入之后，即恢复了搜索功能。
下面附上正常win7系统导出的三个项的reg文件内容：
1、04731B67-D933-450a-90E6-4ACD2E9408FE.reg：
