The environment variable $env:Path lists all paths that are included in the Windows search path when you launch an application. Likewise, $env:PSModulePath lists all paths PowerShell searches for PowerShell modules (and includes in its module auto-loading).

These variables contain semicolon-separated information. Use the operator -split to view the paths separately:

PS> $env:path -split ';' C:\Windows\system32 C:\Windows C:\Windows\System32\Wbem C:\Windows\System32\WindowsPowerShell\v1.0\ PS> $env:PSModulePath -split ';' C:\users\DAIC\My Documents\WindowsPowerShell\Modules C:\Windows\system32\WindowsPowerShell\v1.0\Modules\

驱动器，俗称盘符，c：   d：  这个样子。
---------------------------------------------------------
powershell帮我们把注册表的相关路径
HKEY_CURRENT_USER
HKEY_LOCAL_MACHINE
映射成了盘符：
hkcu：      
hklm：               
-------------------------------------------------------------
把环境变量映射成了盘符
env：


所以你想要获取环境变量，用：

dir     env:      即可
--------------------------------------------------------
几个例子：

dir env:userprofile     -----显示用户目录如  C:\Users\user001
$aaa = (dir env:userprofile).value     ------赋值给变量aaa
