April Fools joke

This IS NOT my code it was made by 'Hothr' i just reposted because i thouht it was fun thing to do😊😊

; April Fools Script 2009
; Made by Hothr, March 2009
;
; FEATURES:
; Doesn't do anything until 10am on april 1st.
; Insalls itself to startup section, and runs itself.
; Deletes itself from startup when Windows+0 is pressed, or after April 1st.
;
; JOKES:
; Slowly makes the mouse "drift" when user has been idle.
; Plays logoff and shutdown sounds (unmute + max volume) when backspace or del are pressed
; Recommends shaking the mouse to fix the problem.
;
; Now, go compile this and run it on eveyone you know's computer!
;

SendMode Input  ; Recommended for new scripts due to its superior speed and reliability.
SetWorkingDir %A_ScriptDir%  ; Ensures a consistent starting directory.
