Delete System32
Delete System32 is a classic 2000s trolling scheme that tricks unsuspecting Windows users into erasing the System32 folder, a core directory their operating system needs to run. The prank took hold on 4chan in late 2006 and is now shorthand online for any deliberately harmful fake advice given to inexperienced PC users.
Overview
Delete System32 is a trolling scheme where pranksters convince inexperienced Windows users to erase the System32 folder, a directory Microsoft's operating system needs to function3. The joke plays on users who don't know what the folder does and follow bad advice framed as a speed boost or virus removal tip. Once the directory is wiped, Windows breaks so badly that basic operations stop working.
The prank typically appears as a helpful suggestion, a fake anti-virus warning, or a batch file disguised as a utility. Windows includes safeguards that block direct deletion during normal use, so trolls share workarounds using the command prompt or scripts with @echo off headers that hide what is running. The line 'delete System32' is now shorthand online for any deliberately destructive fake advice offered to newcomers1.

The setup is scripted, not templated. The common convention is a helpful frame (speed boost, virus fix, defrag) followed by instructions or a batch file that quietly destroys the system. Modern usage often skips the actual trick and drops 'delete System32' as sarcastic shorthand for terrible tech advice.
