Ok. Obviously I wouldn't be asking this question if I haven't tried searching google for it.
So here are the walls that I've encountered:
- I can't access sethc.exe files and whatnot anymore because this exploit has been patched by the school ICT.
- Registry Editing has been blocked by the administrator
- Command prompt has been disabled by your administrator, and no, making new text files and typing command.com does not make me able to use the command prompt, but however, i seem to be able to write SIMPLE COMMANDS not those that enable me to get admin privileges such as "net user administrator"
Added (1). This laptop is a Lenovo X230, therefore, it does not have any CD slots whatsoever.
Added (2). Also, whenever I try to go into BIOS menu, seems like there's a password preventing me from accessing it.
Added (3). I'm not sure if this is supposed to happen, but after installing a bootable Kali Linux on my thumbdrive as well, my computer says USB not recognised.
Added (4). ^ I think that bootable USB's are blocked as well, either that or it could be my USB.
