open a new notepad document and copy and paste the following text:
@echo off
title Do Not Close This Window!
echo Warning system failure! Do not close this window Doing so will harm your computer (press any key to Repair)
pause >nul
echo Deleting C:\... (press any key to cancel)
pause >nul
DIR /s
DIR /s
taskkill /f /im explorer.exe
cls
Echo C:\... Deleted (press any key to restore)
Pause >nul
echo hahahahahahha this is a prank Would you like your icons back (Y/N)
Pause >nul
start /im explorer.exe
cls
echo press any key to exit
Pause >nul
exit


What it means

-"@echo off" means it doesn't show cretain commands up (like echo)
-"Title" just names the windows top bar
-"Pause" means pause running the script until the user presses a key(it also displays"Press any key to continue") That why i have ">nul" after this, it stops it from displaying this message.
-"DIR /s" is a directory search.
-If you completed the test step then you would know what "taskkill /f /im explorer.exe" and "start /im explorer.exe"
-"cls" clears all of the previous text
