System32 is the main importance of Progressbar95, and is known for being a boss. System32 appears in levels that have a 5 or a 9 as their first number. Deleting System32 in ProgressDOS will grant you the "Hello, Dave!" achievement and will trigger a BSOD before forcing you to tap 200 times to re-activate the Progressbar95 systems. After deleting System32 and going on a new level will replace the Decompiler gun options with the System32 pop-up, telling the user that he was killed by the user.
