How To Make Windows More Secure Against Buffer Overflows

Bit protectionI recently found a great tutorial on how to make Windows Vista and XP more secure. By default Windows Vista and Windows XP SP2 or above have measures to prevent buffer overflows and memory corruption. Data Execution Prevention (DEP) is one of these measures Microsoft implemented. The problem with DEP is that you need to configure it right. The video I found takes you through the process of configuring it right both for Windows Vista and XP.

Here is the tutorial. It is really worth taking a look at.

Bypassing BIOS password protection

Securing your own computer is very important and most people rely on BIOS passwords to protect their computer. But this is a huge mistake since anyone with a little bit of knowledge is able to bypass it easily.

Bypassing BIOS password protected computers

Most BIOS chips have built-in master passwords or hidden routes which enable you to bypass the password protection in case you lost or forgot your password.

Master passwords
There are several web sites that list all the BIOS master passwords, here is one of them. You can also just google “BIOS master password list” and you will find tons of lists.

It is not guaranteed that these master passwords work because of the different BIOS chips but there is a pretty good chance that they will.

Bypassing it the other way
You can also bypass it if you are already running Windows( I acutally don’t recommend doing this since it can be harmful to your BIOS, only use it if you know what you are doing). Open the command prompt cmd.exe . There enter:
Debug [Enter]
o 70 17 [Enter]
o 71 17 [Enter]
q [Enter]

This will restart the computer.

Taking screenshots under Windows

I recently needed to take screenshots in Windows so I thought I give you an introduction to taking screenshots under Windows. It is really easy so I’m gonna keep it short:

If you want to take a screenshot of the desktop you have to press “Print Screen” on your keyboard. You still don’t have a screenshot since all what Windows does is copy it to the clipboard. Open up Paint and press “Crtl V”. This will paste the screenshot into Paint. Here you have your screenshot.

If you want to take a screenshot of a single window you have to press “Alt Gr Print Screen” and then do the same mentioned above.
