dll - Is the order of loading .dlls using %PATH% is guaranteed?

Question

When I try to load a .dll then the application first try to load the .dll from their local folder, if it is not there they try to load it using the %PATH% environment variable.

I don't mind if the OS is doing any other searches, but I am interested in the order of the search in the %PATH% environment variable.

Now, let's assume I have two versions of theis dll, and both pathes of those dlls are in the %PATH% environment variable.

Am I guaranteed that the first path that is containing the .dll in the %PATH% environment variable, is the path which the .dll will be loaded from?

更新：

Windows 将按照它们出现在 PATH 变量中的顺序进行搜索。请注意，完整的 PATH 变量由两部分组成：

系统：HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment\PATH

然后附加当前用户的 PATH ： HKEY_CURRENT_USER\Environment\PATH
