xp系统 窗口上方工具栏不见了怎么解决?

1、复制以下内容
[version]
Signature=$CHICAGO$[defaultinstall]addreg=My.add.reg[My.add.reg]HKCR,Folder\shell,,0,"explore"HKCR,Folder\shell\explore,BrowserFlags,0x00010001,34,HKCR,Folder\shell\explore,ExplorerFlags,0x00010001,33,HKCR,Folder\shell\explore\command,,0x00020000,"%SystemRoot%\Explorer.exe /e,/idlist,%I,%L"HKCR,Folder\shell\explore\ddeexec,,0,"[ExploreFolder("""%l""", %I, %S)]"HKCR,Folder\shell\explore\ddeexec,NoActivateHandler,0,HKCR,Folder\shell\explore\ddeexec\application,,0,Folders,HKCR,Folder\shell\explore\ddeexec\ifexec,,,"[]"HKCR,Folder\shell\explore\ddeexec\topic,,,"AppProperties"HKCR,Folder\shell\open,BrowserFlags,0x00010001,16,HKCR,Folder\shell\open,ExplorerFlags,0x00010001,18,HKCR,Folder\shell\open,openrFlags,0x00010001,33,HKCR,Folder\shell\open\command,,0x00020000,"%SystemRoot%\Explorer.exe /idlist,%I,%L"HKCR,Folder\shell\open\ddeexec,,0,"[ViewFolder("""%l""", %I, %S)]"HKCR,Folder\shell\open\ddeexec,NoActivateHandler,0,HKCR,Folder\shell\open\ddeexec\application,,0,Folders,HKCR,Folder\shell\open\ddeexec\ifexec,,,"[]"HKCR,Folder\shell\open\ddeexec\topic,,,"AppProperties"

2、在桌面点鼠标右键-新建-文本文档，打开文本文档粘贴上面的内容到文本文档

3、点击文本文档菜单栏的文件-选择另存为

4、对话框中的保存类型点开选择所有文件，文件名不用改在后面加上扩展名.inf。然后选择任意位置保存

5、找到刚才保存的inf文件，在文件上面点击右键选择安装。过几秒菜单栏工具栏会出现。没有出现重启电脑即可
