Powershell - 幫助我們的CMDB問題 - 意見？

Question

最近我自學了Powershell。這是一個艱難的2周和大量的閱讀，但我越來越好。我在工作上有一些壓力來幫助我們糾正我們的CMDB。我們距離擁有真正的解剖/資產管理系統約7個月。我們現在有很多依靠Powershell的理由，並且在我們獲得管理系統之前，我們試圖清理一團糟。無論如何，我創建了一個腳本，爲我們提供了大量信息。我們有大約3000件物品/件，我們需要儘可能多的信息。無論如何，我創建了一個腳本。到目前爲止，它運作良好，但我想從專家的意見或任何建議。我覺得我做了一個體面的工作，只用了兩週的時間，但我真的想知道別人的想法。

我注意到的一件事：帶有IE9和Windows的Windows 7盒子不會返回IE版本的值。有人知道爲什麼

命名空間root\CIMV2\Applications\MicrosoftIE一直removed starting with Windows Vista（見注在博客文章的末尾）。您應該能夠從註冊表中讀取版本號：

$hive = [UInt32]'0x80000002' 
$key = 'SOFTWARE\Microsoft\Internet Explorer' 

$reg = [WMIClass]"\\$computer\root\default:StdRegProv" 
$ieVersion = $reg.GetStringValue($hive, $key, 'Version').sValue
