电脑任务栏中的图标突然变大了，看起来很模糊，和分辨率好像没关系，桌面上的图标没变，请问怎样变过来？

把下面内容复制到新建立的记事本，并存文件名称为"任务栏修复.vbs",运行"任务栏修复.vbs"尝试修复,OK.

Set WSHShell = WScript.CreateObject("WScript.Shell")
Message = "本脚本用于修复Windows XP中当最小化程序时，无法在任务栏显示图标的问题。"& vbCR & vbCR
Message = Message & "为了正常工作，本脚本将关闭和重启 Windows Explorer 外壳，这个操作不会损坏你的系统。" & vbCR & vbCR
Message = Message & "请关闭所有杀毒软件的实时监控！并保存所有打开的文件。"& vbCR & vbCR
Message = Message & "是否继续？"

X = MsgBox(Message, vbYesNo+vbExclamation, "注意")

If X = 6 Then

On Error Resume Next

Else

End If

这是恢复任务栏的命令，你先恢复一下试试。

这样啊 挺好弄得 记住啊！
运行regedit.exe打开注册表编辑器，找到HKEY_CURRENT_USER\Control Panel\Desktop\WindowMetrics，在右边的窗口中找到字符串值：“Shell Icon Size”，改变其值就可以改变图标的大小。一般是“32”这个数值。注意修改注册表前请事先备份注册表。

我的内容比较简单。昨天出了一样的问题，不管什么原因造成的只要右击桌面-属性-外观-字体大小。切换大再换回正常就可以了。希望对有这个困惑的朋友有帮助。
