我是靠谱客的博主霸气摩托，这篇文章主要介绍Delphi修改操作注册表权限的代码，现在分享给大家，希望可以做个参考。

需要uses jclwin32, AccCtrl; 此文件需要安装JCL

复制代码代码如下:

 
function AllowRegKeyForEveryone(Key: HKEY; Path: string): Boolean; 
var 
WidePath: PWideChar; 
Len: Integer; 
begin 
case Key of 
HKEY_LOCAL_MACHINE: 
Path := 'MACHINE' + Path; 
HKEY_CURRENT_USER: 
Path := 'CURRENT_USER' + Path; 
HKEY_CLASSES_ROOT: 
Path := 'CLASSES_ROOT' + Path; 
HKEY_USERS: 
Path := 'USERS' + Path; 
end; 
Len := (Length(Path)+1)*SizeOf(WideChar); 
GetMem(WidePath,Len); 
MultiByteToWideChar(CP_ACP, MB_PRECOMPOSED, PChar(Path), -1, WidePath, Len); 
Result := SetNamedSecurityInfoW(WidePath, SE_REGISTRY_KEY, 
DACL_SECURITY_INFORMATION, nil, nil, nil, nil) = ERROR_SUCCESS; 
FreeMem(WidePath); 
end;
