Win7咋把我桌面图标给“吞”没了？

Windows7之家（www.908098.com）：Win7咋把我桌面图标给“吞”没了？
前段时间，有运行最新一代客户端操作系统Windows 7的用户表示，他们桌面上的数个快捷方式无缘无故地完全消失了。
对此，微软表示，这是预期之中的事情，是Windows7设计者在Windows7中所添加的设计。在默认情况下，只要System Maintenance troubleshooter（系统故障维护）检测到桌面的快捷方式已经无效了，将会自动将其删除。

微软发表声明表示，每周，System Maintenance troubleshooter（系统故障维护）都会对操作系统进行维护，期间，System Maintenance troubleshooter（系统故障维护）可能会自动修复错误问题，也有可能会通过行动中心报告问题。当检测到用户计算机桌面上有超过4个无效的快捷方式的时候，System Maintenance troubleshooter（系统故障维护）将会自桌面移除所有的无效快捷方式。

微软指出，在删除桌面快捷方式的时候，Windows7的System Maintenance troubleshooter（系统故障维护）是具有一定的限制的。当无效的桌面快捷方式少于4个或等于4个的时候，System Maintenance troubleshooter（系统故障维护）并不会对其进行删除。

此外，如果用户不想无效桌面快捷方式被删的情况发生的话，也可以禁用System Maintenance troubleshooter（系统故障维护），按照以下步骤执行即可——
1、点击左下角开始按钮，在搜索框中输入“疑难” 两个字，然后点击“疑难解答”；
强烈建议Win7新手朋友们阅读《“我是Windows7高手”之第一个秘密》这篇软媒的原创文章。

2、在跳出来的控制面板的“疑难解答”窗口里面，点击左侧的“更改设置”——

3、计算机维护那儿，选择“禁用”，在其他设置里面，你可以去掉“允许在启动时”立即开始排除故障那个勾选框。

好了，到这儿就彻底解决了。

微软指出，正常情况下，Windows用户经常会创建无效的快捷方式，例如，当USB设备没有连接到计算机上的时候，为其创建的桌面快捷方式则视为无效。

Windows 7 RTM Eats Desktop Shortcuts
Especially if they are broken
Windows 7 RTM can eat up some of the desktop shortcuts created by end users, Microsoft explained. Customers running the latest iteration of the Windows client have reported that in certain scenarios shortcuts that they placed on the desktop disappeared altogether. According to the Redmond company, this is expected, by design, behavior in Windows 7. At fault is the System Maintenance troubleshooter that will delete all shortcuts from the desktop as long as they are considered broken.

“The System Maintenance troubleshooter performs a weekly maintenance of the operating system. The System Maintenance troubleshooter either fixes problems automatically or reports problems through Action Center. When there are more than four broken shortcuts on the desktop, the System Maintenance troubleshooter automatically removes all broken shortcuts from the desktop,” Microsoft stated.

According to the software giant, the System Maintenance troubleshooter has a certain limit that triggers it to delete broken shortcuts. Microsoft informs that keeping the number of broken shortcuts on the desktop to no more than four ensures that they won’t be touched. But place five broken shortcuts on the Windows 7 desktop and they will be deleted.

“If you must have more than four broken shortcuts on your desktop, you can disable the System Maintenance troubleshooter. If you disable the System Maintenance troubleshooter, all the maintenance tasks that it performs are disabled. To disable the System Maintenance troubleshooter, follow these steps: click Start, and then click Control Panel. Under System and Security, click Find and fix problems. On the left navigation pane, click Change settings. Set Computer Maintenance to Off,” Microsoft added.

The Redmond company explained that users could frequently create Windows 7 desktop shortcuts that were broken. “For example, a desktop shortcut for a USB device may be regarded as broken if the USB device is not connected when the System Maintenance troubleshooter performs its maintenance,” the software giant explained. This behavior is by design, as already mentioned, so users should not expect a fix.
