完美解决ThinkPad 在Win7系统下弹出USB等反应慢的方法

前段时间在水窝新买了ThinkPad x201 PL2，总觉得安装的WIN7镜像没有原版的系统恢复功能不爽，于是下载了一个原版的恢复光盘进行了原版恢复，但是相信各位使用过 ThinkPad  Win7恢复盘安装过系统的都有点很不爽的感觉，那就是“安全删除硬件及弹出媒体”时那龟速，打开“设备和打印机”时那龟速，打开任务栏那“来弄偶Link"时那龟速,实在是让大家受够了,今天把我在网上找到的解决办法分享给大家,保证1.2秒内打开上述功能。
     特别提示:
     1、只适合用ThinkPad Win7恢复盘所安装的系统(不管是32位还是64位,也不管是什么语言的系统更不管是啥机型)；
     2、注意：确保“C:\ProgramData\Lenovo\LenovoTvtTools”下的文件都还在。
     新出的恢复盘包括64位的，似乎都没解决这问题，造成慢的原因在于Lenovo ThinkVantage Tools下的*.devicemetadata-ms文件与WIN7原有的文件有重复或冲突，该方法是将所有的*.devicemetadata-ms文件先删除，再重新导入Lenovo ThinkVantage Tools下的*.devicemetadata-ms文件，就可以解决这个问题。
     如果“C:\ProgramData\Lenovo\LenovoTvtTools”下的文件有丢失的，转到C:\ProgramData\Microsoft\Windows\DeviceMetadataStore下各文件夹中把最大最新的devicemetadata-ms文件留着，别的都删除即可；
      如果“C:\ProgramData\Lenovo\LenovoTvtTools”下的文件还完整的，将以下相关内容（蓝色的部分）COPY到新建的文本文档然后另存为.bat 的文件运行即可(没办法，支持的可上传附件格式太少了，只能大家自己处理了），注销重登录后定生效。我试过了，确实可用
