Yeah, deleting System32 is the best way to brick the PC.

 

 

I plan on bricking some of the PC's in schools for the lulz.

Are you asking because you want to make the PC unuseble or because you want to play around in cmd but don't want to break anything?

Hiren's Boot CD.

Master Boot Record editor.

Delete MBR.

 

 

 

Done.

Alternatively, you could also enter the BIOS flash mode, and pull the power plug once it starts to erase the blocks. That can be done from CMD console or from the OS with the MOBO's software.

ipconfig /release

Good prank. Deleting system32 is a bit fucked up, guys. We don't even know his intentions. 

Downloading a virus helps.

lmao, remember crashme.com or something like that. funny ol'days...

Fork bomb that shit with a batch file. :D
