새로운 미용실을 가다.

Recently, I changed the lambda code to capture a local variable, and then the code didn't compile.
What I found was that only a lambda without capture can be converted to a function pointer.

[expr.prim.lambda]

Usually, the parent process is the process that creats the new process. But you can change this behavior by setting STARTUPINFOEX.lpAttributeList.

HANDLE hParentProcess{ nullptr };
LPPROC_THREAD_ATTRIBUTE_LIST attrList{ nullptr };


// Initialize LPPROC_THREAD_ATTRIBUTE_LIST
hParentProcess = OpenProcess(PROCESS_CREATE_PROCESS, FALSE, parentProcessId);

SIZE_T attrListSize = 0;
InitializeProcThreadAttributeList(nullptr, 1, 0, &attrListSize);
attrList = (LPPROC_THREAD_ATTRIBUTE_LIST)malloc(attrListSize);

InitializeProcThreadAttributeList(attrList, 1, 0, &attrListSize);

UpdateProcThreadAttribute(attrList, 0, PROC_THREAD_ATTRIBUTE_PARENT_PROCESS, &hParentProcess,
	sizeof(hParentProcess), nullptr, nullptr);


// Set LPPROC_THREAD_ATTRIBUTE_LIST to the STARTUPINFOEX
STARTUPINFOEX  si = { sizeof(si) };
si.StartupInfo.cb = sizeof(si);
si.lpAttributeList = attrList;

PROCESS_INFORMATION pi = { 0 };


CreateProcess(nullptr, argv[1], nullptr, nullptr, FALSE, EXTENDED_STARTUPINFO_PRESENT, nullptr, nullptr, &si.StartupInfo, &pi);

If you want to open 'This PC\All Control Panel Items\Programs and Features'
First you need to convert each items to GUID

• This PC -> 20d04fe0-3aea-1069-a2d8-08002b30309d
• All Control Panel Items -> 21ec2020-3aea-1069-a2dd-08002b30309d
• Programs and Features -> 7b81be6a-ce2b-4676-a29e-eb907a5126c5

Then launch exporer.exe with /separate paramter

For example:

C:\Windows\explorer.exe /separate, ::{20d04fe0-3aea-1069-a2d8-08002b30309d}\::{21ec2020-3aea-1069-a2dd-08002b30309d}\::{7b81be6a-ce2b-4676-a29e-eb907a5126c5}

Then the above process will be terminated and the below process shows up with ' Programs and Features'

C:\WINDOWS\explorer.exe /factory,{75dff2b7-6936-4c06-a8bb-676a7b00b24b} -Embedding

If you want to launch explorer.exe as your descendant process, there is a way

1. Run: C:\WINDOWS\explorer.exe /factory,{75dff2b7-6936-4c06-a8bb-676a7b00b24b} -Embedding
   • This process is your descendant process and it is invisible.
2. Run: C:\Windows\explorer.exe /separate, ::{20d04fe0-3aea-1069-a2d8-08002b30309d}\::{21ec2020-3aea-1069-a2dd-08002b30309d}\::{7b81be6a-ce2b-4676-a29e-eb907a5126c5}
   • This process will be terminated and 'Programs and Features' will be showed in the previous explorer.exe.
   • But if there is one more explorer.exe /factory, there is no gurantee which one shows 'Programs and Features'.
