怎样让WinPE也有快速压缩功能
著名的压缩软件7-Zip是一款GNU/LPGL协议下分发的免费软件,可以说是目前最有希望成为zip、rar之后的下一个主流压缩格式的文件压缩格式了。下面我们就来看看如何把为pe增加7z右键功能，当然方法可能有许多种，只介绍其中的一种方法以供参考。
首先把7z.exe、7z.dll、7-zip.dll、7zG.exe四个文件拷贝到system32文件夹下。
然后在REGDOC.CMD(也有可能是别的名字，或者没有)中加入如下句子：
rem 关联7z

reg add "HKU/.DEFAULT/SessionInformation" /f /v "ProgramCount" /t REG_DWORD /d 4
