tl/dr：我正在寻找一种方法来以当前从以Local System Account.

长版：

跟进：从作为本地系统帐户启动的程序中获取当前用户名

我的程序是从运行为Local System Account.

此服务在 Windows 启动时启动，基本上为某些硬件按钮提供功能，例如显示屏幕键盘。我的程序也分配给其中一个按钮，但它仅在实际用户登录时可用。

它所做的是使用硬件相机拍照并将其存储在文件系统的某个位置，这工作正常，但我无法将图片存储在网络路径上，这是可以理解的，因为这样做需要身份验证。

如果程序以登录用户的身份直接启动，则此身份验证可用，并且将文件存储在网络路径上工作正常。

有什么办法可以解决这个问题吗？

我首选的解决方案是以当前登录的用户身份启动程序，而不在某处存储密码和用户名。

you have to use CreateProcessAsUser. A guide can be found here and here. Hope this helps.
