许多软件的安装会在注册表注册自己。这里段代码能很好的从本地或远程注册表主键获取已安装的32位或64位软件。脚本也可以作为一个很好的远程读取注册表的例子:
# NOTE: RemoteRegistry Service needs to run on a target system! $Hive = 'LocalMachine' # you can specify as many keys as you want as long as they are all in the same hive $Key = 'SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall', 'SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall' # you can specify as many value names as you want $Value = 'DisplayName', 'DisplayVersion', 'UninstallString' # you can specify a remote computer name as long as the RemoteRegistry service runs on the target machine, # you have admin permissions on the target, and the firewall does not block you. Default is the local machine: $ComputerName = $env:COMPUTERNAME # add the value "RegPath" which will contain the actual Registry path the value came from (since you can specify more than one key) $Value = @($Value) + 'RegPath' # now for each regkey you specified... $Key | ForEach-Object { # ...open the hive on the appropriate machine $RegHive = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey($Hive, $ComputerName) # ...open the key in that hive... $RegKey = $RegHive.OpenSubKey($_) # ...find names of all subkeys... $RegKey.GetSubKeyNames() | ForEach-Object { # ...open subkeys... $SubKey = $RegKey.OpenSubKey($_) # ...and read all the requested values from each subkey # ...to store them, use Select-Object to create a simple new object $returnValue = 1 | Select-Object -Property $Value $Value | ForEach-Object { $returnValue.$_ = $subkey.GetValue($_) } # ...add the current regkey path name $returnValue.RegPath = $SubKey.Name # return the values: $returnValue # close the subkey $SubKey.Close() } # close the regkey $RegKey.Close() # close the hive $RegHive.Close() } | Out-GridView
心得:
该脚本我们学习到了如何去读取一个注册表,中间“$returnValue=1|Select-Object -Property $Value”这种用法让我们学习到如何快速创建一个带属性的集合,$Value = @($Value) + ‘RegPath’又让我们学习到如何追加集合,同时多重管道+嵌套循环的应用也充分反应出作者清晰的编程思路,此文不亏是一篇好的基础范例文章。
