Now that's a real classic logo that has not changed much from Windows 3.1 to Windows 2003.
Almost all the official start buttons never had the right-angled image, probably because it takes up more space.
If you have the angled image .png logo that you want to go top of an XP start button,
you will feel more satisfied if you do it yourself.
People have uploaded all kinds of XP start button versions:

You just need an image editor like Adobe or a free one that can resize and paste a transparent .png image onto the start button image.
I only did a Luna start button and it may not be the correct type that you want.
If so, try a different one on your own.
