Free Access To Websites Without Registering

Go to

http://bugmenot.com/

and type the URL of the website you want to log into.
Examples:

etcetera.

Another (and better) way is changing the user agent of your browser to:
Googlebot/2.1+

http://www.googlebot.com/bot.html

This is very easy in Mozilla’s Firefox. Download and install the User Agent Switcher from

http://www.chrispederick.com/work/firefox/useragentswitcher/

and add the Googlebot user agent.

so you want to change your mac address

for this you need to have a little bit knowledge on windows registries

Step1
click on startbutton and click on Run and type regedit

Change Your MAC Address (Windows 2k/xp)
This setting will change the MAC address of the NIC card.
Go to “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002BE10318}. Double click on it to expand the tree. You should see it starts with 0000, then 0001, 0002, 0003 and so on.
Now go through each subkey that starts with 0000. Click on 0000, check DriverDesc keyword on the right to see if that’s the NIC you want to change the MAC address. The DriveDesc should match the Description of the NIC that to be chaged Example : DriveDesc REG_SZ D-Link DFE-520TX PCI Fast Ethernet Adapter. Now create REG_SZ with value name “NetworkAddress” .In the value data give the new MAC address .
System Key: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E972-E325-11CE-BFC1-08002BE10318}]
Value Name: NetworkAddress

Don’t like having ‘Shortcut to…’ appended to every Shortcut? You’re not alone. With this tip you can stop Windows for adding this text when creating links.

Open your registry and find the key below.

Create a new BINARY value name ‘link’, of modify the existing value, to equal ’00 00 00 00′ to have the Shortcut text disabled.

TIP: This restriction can be used either on a user by user basis by adding it to HKEY_CURRENT_USER or on a computer wide basis by adding it to HKEY_LOCAL_MACHINE.

Registry Settings:
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer]
System Key: [HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer]
Value Name: link
Data Type: REG_BINARY (Binary Value)
Value Data: (00 00 00 00 = No Shortcut Text)
