To operate a registry key with permission restrictions under Win2K

In the 2k system operation registry, found that some of the health must have permission problems;

Look at you big stickers, unfortunately not a suitable result;

Some people say: You can improve the user's rights, but in fact it seems to be not very useful;

After a hard, hard, hard struggle; Finally found some good dynamic on MSDN;

I don't want to be alone, (eh, I don't like someone, good things hide where they forget)

Sort out some useful things for some people: Hey, the code is as follows:

Serious suggestion: Everyone put the good things into the bar!!!!!!
