为什么/如何隐藏在 Regedit 中但在 PowerShell 中可见的注册表项? [英] Why/how are Registry Entries Hidden in Regedit but visible in PowerShell?

问题描述

我正在使用新的属性架构，并且习惯于在注册或注销新版本时检查注册表.检查此项的主要位置之一是 HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\WINDOWS\CURRENTVERSION\PROPERTYSYSTEM\PROPERTYSCHEMA.

I'm working with a new property schema, and have been in the habit of checking the registry when I register or unregister a new version. One of the primary places to check this is HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\WINDOWS\CURRENTVERSION\PROPERTYSYSTEM\PROPERTYSCHEMA.

有趣的是，我偶尔会无法访问 Regedit 中的此注册表位置.我看到了这个(注意没有 PropertySchema):

Interestingly, I occasionally lose access to this registry location in Regedit. I see see this (note the absence of PropertySchema):

我知道架构仍然注册，因为我可以使用 prop.exe 工具和 propschema SDK 示例应用程序来描述它们.这些属性在 Windows 资源管理器和搜索中可用.

I know the schemas are still registered, because I can use the prop.exe tool and propschema SDK sample application to describe them. The properties are available in Windows Explorer and in Search.

此外，我可以使用 PowerShell 列出此配置单元的内容:

Also, I can use PowerShell to list the contents of this hive:

C:\Users\carlton> cd hklm:
HKLM:\>
C:\Users\carlton> cd hklm:
HKLM:\> cd SOFTWARE\MICROSOFT\WINDOWS\CURRENTVERSION\PROPERTYSYSTEM\PROPERTYSCHEMA
HKLM:\SOFTWARE\MICROSOFT\WINDOWS\CURRENTVERSION\PROPERTYSYSTEM\PROPERTYSCHEMA> dir


    Hive: HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\WINDOWS\CURRENTVERSION\PROPERTYSYSTEM\PROPERTYSCHEMA


Name                           Property
----                           --------
0000                           (default)  : C:\Program Files\Internet Explorer\ie9props.propdesc
                               SchemaId   : {D9B5ABA1-5E8A-4902-B6A1-50B3C0311C2E}
                               URI        : ie9props.propdesc
                               CompactURI : 5376bae4b39f43768806afcb6b8ff5464bf9c989d1a819c6e6d99ba1e8ce2512
0001                           (default)  : C:\Program Files\Microsoft Office\Office14\Custom.propdesc
                               SchemaId   : {537AAAB1-1D85-48DC-A99E-16EB8C309FE5}
                               URI        : custom.propdesc
                               CompactURI : 2e3be58e5cbbc0da093956b46a3905f11cf0f5bbf11987a8619e25f7261ee8be
0002                           (default)  : C:\apps\MSOffice\Office14\VisioCustom.propdesc
                               SchemaId   : {18503526-0466-4942-AC6E-41C1D380EABA}
                               URI        : visiocustom.propdesc
...

无论如何，我不明白这是怎么发生的，我是否应该担心.从同事的机器导出此密钥并重新导入它会暂时有所帮助，因为它会在 Regedit 中显示隐藏/丢失的密钥(即使它们不在我同事的机器上).

Anyway, I don't understand how this happens, and whether I should be worried about it. Exporting this key from a colleague's machine and re-importing it can temporarily help, as it will show keys in Regedit that were hidden/missing (even if they weren't on my colleague's machine).

推荐答案

Harry Johnston 的直觉是正确的.我从带有路径 c:\windows\regedit 的命令行重新运行 regedit，我再次看到了 HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\PropertySystem\ 下的预期内容属性架构.我可以发誓它也没有显示它，但显然它现在正在工作.

Harry Johnston's intuition was correct. I re-ran regedit from a command line with the path c:\windows\regedit, and I once again see what I expected under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\PropertySystem\PropertySchema. I could've sworn it wasn't showing it either, but it's working now, apparently.

我通过从 64 位和 32 位 regedit 导出父密钥 (PropertySystem) 并运行 Beyond Compare 来确认.32 位版本中确实没有 propdesc 文件.

I confirmed as much by exporting the parent key (PropertySystem) from the 64-bit and 32-bit regedit's and running Beyond Compare. The propdesc files are verily not there in the 32-bit version.
