MATLAB: Is there a way to use WINQUERYREG or another MATLAB feature to list the names of subkeys under a given key in the Windows registry

MATLAB

I want to list the subkeys under a given key in the Windows registry. I want to know if there is a function to do this in MATLAB.

Best Answer

The ability to query the subkeys under a given key in Windows registry is not available in MATLAB.

To work around this issue, SYSTEM command can be used used with the Windows query which queries the subkeys of a particular key as follows:

[ok,txt] = system('reg query HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall')

The output can be parsed through to list the names of subkeys.

Since we are unable to reproduce the issue on our end, we suggest the following:

1. If "ProductId" is available in your registry, the MATLAB command WINQUERYREG will return it. For example, on my machine:

>> winqueryreg('HKEY_LOCAL_MACHINE', 'SOFTWARE\Microsoft\Windows NT\CurrentVersion', 'ProductID')
ans =
00392-918-5000002-85980

Make sure there is a space between Windows and NT.

2. If (1) fails, you can try the following .NET code in MATLAB to check the registry entries:

>> NET.addAssembly('mscorlib');
>> root = Microsoft.Win32.Registry.LocalMachine;
>> root.OpenSubKey('SOFTWARE\Microsoft\Windows
NT\CurrentVersion').GetValue('ProductId')
ans = 
00392-918-5000002-85980

3. If neither works, try the same code from a VB app or a C# app on the problem machine.

4. If that still does not work, the issue is with the machine setup, and your best bet would be to contact your system administrator or Microsoft.
