Change the regional and language setting of the windows

I want to change the regional and language 开发者_运维百科setting of the windows from the vb 6.0. Is there any way to change the regional and language setting to the windows' default like in the picture.

If there is it would be a bad idea.

These settings belong to the user, not your programs.

I think it is acceptable to change the settings while the program is running then restore the settings to old values. Or even ask the user for permission. Some times, it's necessary to do that.
