powershell脚本设置自动获取或者静态IP

代码如下

#查看权限 
#Get-ExecutionPolicy
# 无执行权限:Restricted
#Set-ExecutionPolicy Restricted
#开启powershell执行权限
#Set-ExecutionPolicy remotesigned 
 
 
######
function judge-IsAdmin {
    return ([Security.Principal.WindowsPrincipal] [Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole(
            [Security.Principal.WindowsBuiltInRole] "Administrator")
}
if (!(judge-IsAdmin)) {
   Write-Host "任意键继续下一步,点是,会管理身份运行powershell窗,若闪退,请开启执行策略(Set-ExecutionPolicy remotesigned)"
   Write-Host "下一步同时会生成相同功能的批处理setmyip.cmd,若不会开启powershell执行策略可以用批处理"
   cmd /c pause
}
