Edge First Tab Error when Opening via System() - c++

Question

When doing
const std::string LaunchStr = "C:\\\"Program Files (x86)\"\\Microsoft\\Edge\\Application\\msedge.exe --profile-directory=\"Profile 1\" C:\\Users\\redacted1\\redacted4.html";
System(LaunchStr.c_str());
Microsoft Edge launches as expected, the loaded profile is the correct one and there is a new tab on redacted4.html. However, the first tab (and the focused one too) is the following url program%20--fast-start%20files%20%28x86%29/Microsoft/Edge/Application/msedge.exe. Which I find weird because nowhere in my code do I write program%20--fast-start%20files%20%28x86%29/.
Why is that? How can I prevent it?

Answer 1

I suggest you try to refer to the sample code below that may help you to launch the MS Edge browser correctly with the correct profile and with the specified URL.
#include <windows.h>
int main()
{
CoInitializeEx(nullptr, COINIT_APARTMENTTHREADED);
SHELLEXECUTEINFOW sei = { sizeof sei };
sei.lpVerb = L"open";
sei.lpFile = L"C:\\Program Files (x86)\\Microsoft\\Edge\\Application\\msedge.exe";
sei.lpParameters = L"--user-data-dir=\"C:\\Users\\<user>\\AppData\\Local\\Microsoft\\Edge\\User Data\\Profile 1\" C:\\Users\\redacted1\\redacted4.html"; // Modify the path for user-profile here...
ShellExecuteExW(&sei);
}
Note: You can type edge://version/ in the address bar of the Edge browser and see the profile path to modify it in the above code sample.
Output:
