Query the Windows registry through batch syntax
提问by Luca Matteis
I'm trying to query a particular registry folder (or whatever you want to call it) to obtain some information.
我正在尝试查询特定的注册表文件夹（或任何您想调用的文件夹）以获取一些信息。
Particularly the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstallfolder contains a list of installed software.
特别是该HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall文件夹包含已安装软件的列表。
The issue is that each software is identified through a random key value like {0001B4FD-9EA3-4D90-A79E-FD14BA3AB01D}instead of the actual software (like Skype).
问题是每个软件都是通过一个随机的键值来标识的，{0001B4FD-9EA3-4D90-A79E-FD14BA3AB01D}而不是实际的软件（如Skype）。
This makes it hard to find the Skypeidentifier because I need to loop through everything inside this Uninstallfolder and check whether the DisplayNamevalue corresponds to Skype(or whatever other application name).
这使得很难找到Skype标识符，因为我需要遍历此Uninstall文件夹中的所有内容并检查该DisplayName值是否对应Skype（或任何其他应用程序名称）。
I need to use batch syntax... this is what I have so far but it doesn't behave the same on different computers, maybe I get different variables assigned based on some erroneous formatting of the reg output? I don't know. Can I use a data structure to contain whatever regoutputs? Anything would work.
我需要使用批处理语法......这是我到目前为止所拥有的，但它在不同的计算机上的表现并不相同，也许我根据 reg 输出的某些错误格式分配了不同的变量？我不知道。我可以使用数据结构来包含任何reg输出吗？什么都行。
@echo off
for /f "tokens=*" %%a in ('reg query HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall') do (
for /f "tokens=2,* delims= " %%b in ('reg query %%a /v Publisher') do (
IF "%%c" == "Skype Technologies S.A." (
for /f "tokens=2,* delims= " %%d in ('reg query %%a /v UninstallString') do (
echo %%e
)
)
)
)
Is there a cleaner and safer way to achieve this in batch?
有没有更清洁、更安全的方法来批量实现这一目标？

It seems me more easy to use
好像我比较好用
reg QUERY HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall /f "Skype Technologies S.A." /s
as a basis for your batch file. It produces a simple output like following
作为批处理文件的基础。它产生一个简单的输出，如下所示
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{D103C4BA-F905-437A-8049-DB24763BBE36}
Publisher REG_SZ Skype Technologies S.A.

Here is a batch script which can extract Uninstall string e.g. MsiExec.exe /X[GUID]from x86/32bit registry keys as well as the software name. The output looks like this. You can add your logic e.g. a IF statement to filter and uninstall the software if you want to.
这是一个批处理脚本，它可以从 x86/32 位注册表项以及软件名称中提取卸载字符串，例如MsiExec.exe /X[GUID]。输出看起来像这样。如果需要，您可以添加逻辑，例如 IF 语句来过滤和卸载软件。
Note: Not all the applications have a MsiExec.exe /Xstring and some MsiExec.exestrings contain MsiExec.exe /Iwhich mean reinstall it. They will be replaced with MsiExec.exe /Xin the script
注意：并非所有应用程序都有MsiExec.exe /X字符串，某些MsiExec.exe字符串包含MsiExec.exe /I，这意味着重新安装它。它们将在脚本中替换为MsiExec.exe /X
Remove ^|findstr "MsiExec.exe"from the script below if you want to list ALL 32bit applications
如果要列出所有 32 位应用程序，请从下面的脚本中删除^|findstr "MsiExec.exe"
MsiExec.exe /X{87D50333-E534-493A-8E98-0A49BC28F64B} SQL Server 2012 Database Engine Services
MsiExec.exe /X{C22613C2-C7A4-4761-A906-116ECD4E7477} SQL Server 2012 Database Engine Services
MsiExec.exe /X{8BC3EEC9-090F-4C53-A8DA-1BEC913040F9} Microsoft .NET Framework 4.6.1 Targeting Pack
MsiExec.exe /X{8C5FB518-E78C-F8F0-BFEC-8EAC65F51003} Windows Assessment Services - Client (Client SKU)
MsiExec.exe /X{90160000-008C-0000-0000-0000000FF1CE} Office 16 Click-to-Run Extensibility Component
MsiExec.exe /X{90160000-008C-0409-0000-0000000FF1CE} Office 16 Click-to-Run Localization Component
MsiExec.exe /X{91361B2A-F741-E591-303B-4EF957F3BAF1} Windows Assessment Toolkit (AMD64 Architecture Specific)
