I accidentally did this when trying to wipe off dust off of my touch pad. Help!

Right click at an open spot of your desktop > click Graphic options ( NOT graphic properties ) > click Rotation > click Rotate to normal.

My screenshot is from Win 10 Pro Insider Preview Build.

If you are not using Win 10 Insider Preview build, you might not have Rotate to Normal option.
In that case, use those "rotate to xx degrees" options.
