There are at least three solutions to help you get back in, I think. One is activate the built-in hidden administrator account offline using Windows installation media:

or promote your standard user to administrator:

The final method is restore your Windows to a previous backup point, or use the Linux Live CD: Ophcrack, Offline NT Password & Registry Editor.
