Powershell:删除所有包含字符串的注册表项 [英] Powershell: delete all the registry keys containing a string

问题描述

我想从以下位置删除所有包含 Python35 的键 (1000+):HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-2\组件

I would like to delete all the keys (1000+) containing Python35 from :HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-2\Components

例如我想删除所有与那个相似的键:

For instance I would like to delete all the keys similar to that one:

• 键名:HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-2\Components\0027CAECCC428F356B8D845FF8331246

名称:0F617A7B1C879BC47865E0155CDD6722

我试过了.

Get-ChildItem -path HKLM:SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-2\Components\ -Recurse | where { $_.Name -match 'Python35'} | Remove-Item -Force

Powershell 运行没有错误，但是当我在注册表中检查它时，密钥仍然存在.

Powershell runs without error,but when I check it in the registry, the keys are still there.

Powershell 以管理员身份运行，管理员拥有密钥 HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-2\Components 的所有权，并且还拥有完全控制权在该键及其子键上.

Powershell is run as admin and Admin has the ownership of the key HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-2\Components and also full control on that key and its subkeys.

推荐答案

试试下面的脚本:

$RE = 'Python35'
$Key = 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-2\Components'
Get-ChildItem $Key -Rec -EA SilentlyContinue | ForEach-Object {
   $CurrentKey = (Get-ItemProperty -Path $_.PsPath)
   If ($CurrentKey -match $RE){
     $CurrentKey|Remove-Item -Force -Whatif
   }
}

如果输出看起来没问题，从 Remove-Item

If the output looks OK remove the -WhatIf paramter from Remove-Item
