How to tell if a Windows app is UWP or win32 through interface or coding?

凯于 1

Now I want to determine whether the office software on my computer is Win32 or UWP by interface or code, but I have not found any effective way. I hope you can brainstorm and thank you for your help~

You can use GetPackageFamilyName

I read the interface documentation you provided, but I still haven't figured out how to distinguish between Win32 and UWP applications. Maybe it's because I don't understand C++ very well, is there a C# or python or other related way to get it?

What's the real problem that you are trying to solve? That is, why do you need to distinguish between the 2?

The problem is that it is necessary to distinguish the types of win32 and uwp for applications on the PC through the program.

GetPackageFamilyName works in C# (P/Invoke) or any language.
I tested on Windows 10 21H1
Non-UWP app return an empty string in packageFamilyName and return APPMODEL_ERROR_NO_PACKAGE as the doc says

The declarations I used for the test (I tested with Notepad (Win32) and Calculator (UWP)) (QueryFullProcessImageName not used here...)

[DllImport("Kernel32.dll", SetLastError = true, CharSet = CharSet.Unicode)] public static extern int GetPackageFamilyName(IntPtr hProcess, ref uint packageFamilyNameLength, StringBuilder packageFamilyName); public const int APPMODEL_ERROR_NO_PACKAGE = 15700; public const int ERROR_INSUFFICIENT_BUFFER = 122; [DllImport("Kernel32.dll", SetLastError = true, CharSet = CharSet.Unicode)] public static extern IntPtr OpenProcess(uint dwDesiredAccess, bool bInheritHandle, int dwProcessId); public const int PROCESS_QUERY_LIMITED_INFORMATION = (0x1000); [DllImport("Kernel32.dll", SetLastError = true, CharSet = CharSet.Unicode)] public static extern bool QueryFullProcessImageName(IntPtr hProcess, int dwFlags, StringBuilder lpExeName, ref uint lpdwSize); [DllImport("Kernel32.dll", SetLastError = true, CharSet = CharSet.Unicode)] public static extern bool CloseHandle(IntPtr hObject);

That's not necessarily the case. I've tested with a few apps (Film and TV, Calculator, Media Player) on a few different devices and they all returned APPMODEL_ERROR_NO_PACKAGE . I'm not certain of the conditions for this to happen though.

It works fine on Windows 10 (22H2)

For example with "Film and TV", I get : "Microsoft.ZuneVideo_8wekyb3d8bbwe"
