解压缩: Vista专有微软更新独立包

MSU文件不支持“/x”类型参数，也不能在Vista之前的系统中运行。要解压缩MSU文件，就需要使用Vista的展开命令，需要用到“-F”参数。

;D:|temp>mkdir msu
;D:|temp>expand -F:* Windows6.0-KB929761-x86.msu d:|temp|msu

以上命令会输出：

Adding d:|temp|msu|WSUSSCAN.cab to Extraction Queue
Adding d:|temp|msu|Windows6.0-KB929761-x86.cab to Extraction Queue
Adding d:|temp|msu|Windows6.0-KB929761-x86-pkgPropertIEs.txt to Extraction Queue
Adding d:|temp|msu|Windows6.0-KB929761-x86.xml to Extraction Queue

此时.cab文件还未解压缩，仍需要继续，命令如下：

; D:|temp>expand -F:* d:|temp|msu|Windows6.0-KB929761-x86.cab d:|temp|msu;

Adding d:|temp|msu|update.mum to Extraction Queue
