1.通过注册列表查看

$Path=@('HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\*','HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\*','HKCU:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\*','HKCU:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\*')$Items=Get-ItemProperty -Path $Path -ErrorAction SilentlyContinue

2.关键字，查找相应软件

$officeList=$Items|Select-object -Property DisplayName,DisplayVersion,UninstallString |Where-Object DisplayName -like "*office*"|Where-Object DisplayName -like "*click-to*"
