How to change the logon screen in windows 7

1. The image you need to set as the background should be a ".jpg" file and it’s size should not exceed "245KB".

2. The image resolution can be anything of your choice. However 1440 x 900 or 1024 x 768 is preferable.After compressing and setting the resolution for your image, save it as backgroundDefault.jpg.

3. You will need to copy this image to

"C:\Windows\system32\oobe\info\backgrounds"

You will need to create that path if it does not already exist on your computer.

4. Now open the Registry Editor (Start -> Run -> Type regedit) and navigate to the following key

"HKLM\Software\Microsoft\Windows\CurrentVersion\Authentication\LogonUI\Background"

If "Background" does not exist rightclick "LogonUI", select New and then Key, and then name it Background. Now locate OEMBackground (listed on the right side). If it does not exist, right-click Background and select New and then DWORD and name it OEMBackground.

5. Double-click on OEMBackground and set the Value Data to 1.

6. Now log-off to see the new logon screen background. If you would like to revert back to the default background, just set the Value Data back to 0.

Aircrack-ng

Aircrack-ng is an 802.11 WEP and WPA-PSK keys cracking program that can recover keys once enough data packets have been captured. It implements the standard FMS attack along with some optimizations like KoreK attacks, as well as the all-new PTW attack, thus making the attack much faster compared to other WEP cracking tools.

In fact, Aircrack-ng is a set of tools for auditing wireless networks.
