In this instructable i will show you how to turn your windows 7 into windows xp (it can be used as a prank) but you can still use everything the same way. by the way the thing in the top right hand corner is an acer touch portal thing. i have it because my computer is touch screen. :D
Step 1: Doing What You Need to Do
now you need to go into control panel then select appearance and personalization then select change theme.
then scroll down to the bottom and choose windows classic theme then it will come up with a splash screen then it will change.
to change it back just click on windows 7 basic theme and it will return to normal.
