Password keys for wireless networks, better known as WEP keys, are a common method for securing wireless networks. These password keys are usually located on the bottom of the wireless router and labeled as WEP keys; however, if this sticker is missing and the WEP key has not been written down or has been forgotten, it is possible to recover the WEP key if it has previously been entered into the computer, and the computer is running the Windows XP Operating System.

Click the "Start" button on the lower left-hand corner of the computer screen. This will open the Start menu.

Click on the "Run" option. The Run command window will appear.

Type "regedit" into the Run command window.

Click the "OK" button. This will launch Windows XP's Registry Editor.

Expand the "HKEY_CURRENT_USER" registry listing.

Scroll down and click on the "Software" entry. The "Software" entry will expand.

Scroll down and locate the "Microsoft" label.

Scroll through the Microsoft label to locate the "WZCSVC" label.

Expand the "WZCSVC" label.

Find and expand the "Parameters" label.

Click on the "Interfaces" label.

Find the WEP key within the "Interfaces" registry.

Write down the WEP key and keep it recorded in a secure place for future use.


Do not change anything within the Registry Editor--such changes may result in software programs or the OS not working properly.
