C++ 使用 Winapi 删除 Windows注册表键值

CodeBlocks 使用 VC2010 编译器，需要指定 AdvAPI32.lib库编译完成

直接删除注册表中某个目录，踩坑两次 注意 \ 符号

#include <stdio.h>
#include <windows.h>
int main()
{
    HKEY hKey = HKEY_CURRENT_USER;
    const char* SubKey = "Software\VB and VBA Program Settings\sRGB";
    int ret = RegDeleteTreeA(hKey, SubKey);
    return ret;
}

//  https://docs.microsoft.com/zh-cn/windows/win32/api/winreg/nf-winreg-regdeletekeyvaluea

//LSTATUS RegDeleteKeyA(
//  HKEY   hKey,
//  LPCSTR lpSubKey
//);

//LSTATUS RegDeleteTreeA(
//  HKEY   hKey,
//  LPCSTR lpSubKey
//);

//LSTATUS RegDeleteKeyValueA(
//  HKEY   hKey,
//  LPCSTR lpSubKey,
//  LPCSTR lpValueName
//);
//  #define HKEY_CLASSES_ROOT ((HKEY) (ULONG_PTR)((LONG)0x80000000))
//  #define HKEY_CURRENT_USER ((HKEY) (ULONG_PTR)((LONG)0x80000001))
//  #define HKEY_LOCAL_MACHINE ((HKEY) (ULONG_PTR)((LONG)0x80000002))
//  #define HKEY_USERS ((HKEY) (ULONG_PTR)((LONG)0x80000003))

删除某些软件注册信息

#include <stdio.h>
#include <windows.h>
int main()
{
    HKEY hKey = HKEY_CURRENT_USER;
    const char* SubKey = "SOFTWARE\Microsoft\Windows\CurrentVersion";
    const char* ValueName = "REG_KR";
    int ret = RegDeleteKeyValueA(hKey, SubKey, ValueName);
    return ret;
}
