查看已安裝軟件

1.通過注冊列表查看

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

2.關鍵字，查找相應軟件

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

a.使用Select-object -Property 獲取需要的屬性

b.使用Where-Object xxx -like 來模糊匹配關鍵字
