Change Your Ip In Less Then 1 Minute

How To: Change Your Ip In Less Then 1 Minute

1. Click on "Start" in the bottom left hand corner of screen
2. Click on "Run"
3. Type in "command" and hit ok

You should now be at an MSDOS prompt screen.

4. Type "ipconfig /release" just like that, and hit "enter"
5. Type "exit" and leave the prompt
6. Right-click on "Network Places" or "My Network Places" on your desktop.
7. Click on "properties"

You should now be on a screen with something titled "Local Area Connection", or something close to that, and, if you have a network hooked up, all of your other networks.

8. Right click on "Local Area Connection" and click "properties"
9. Double-click on the "Internet Protocol (TCP/IP)" from the list under the "General" tab
10. Click on "Use the following IP address" under the "General" tab
11. Create an IP address (It doesn't matter what it is. I just type 1 and 2 until i fill the area up).
12. Press "Tab" and it should automatically fill in the "Subnet Mask" section with default numbers.
13. Hit the "Ok" button here
14. Hit the "Ok" button again

You should now be back to the "Local Area Connection" screen.

15. Right-click back on "Local Area Connection" and go to properties again.
16. Go back to the "TCP/IP" settings
17. This time, select "Obtain an IP address automatically"
tongue.gif 18. Hit "Ok"
19. Hit "Ok" again
20. You now have a new IP address

With a little practice, you can easily get this process down to 15 seconds.

P.S:
This only changes your dynamic IP address, not your ISP/IP address. If you plan on hacking a website with this trick be extremely careful, because if they try a little, they can trace it back

how to edit right click menu

How To
Remove and Add Right-Click Menu Items from Files and Folders

Removing Items

A lot of programs you install will add themselves to the right-click
menu of your files and/or folders. And most times, you have no choice in the
matter and, as a result, your right-click menu can get very long with added
items you don't even use. The last person I was helping with this had a right
context menu so long that the Rename option was no longer visible!

Fortunately, you can easily remove those unwanted menu items, if you
know the registry values to edit. And it's not at all difficult once you know
the keys responsible for the additions.



For Files, the secret lies in the "context menu handlers" under the shellex subkey for "All
Files" which, in the registry, is nothing but an asterisk - like a dos
wildcard, which means the values entered apply to all files. It is at the very
top of the Root key, right here:



HKEY_CLASSES_ROOT\*\shellex\ContextMenuHandlers



Click the the + sign next to the ContextMenuHandlers
key, to expand it.

Now you will see some of the programs that have added items to your right-click
menu. Simply delete the program keys you don't want.

Yup! It's that simple. If deleting makes you uneasy, just export the key before
deleting it. Or, instead of deleting the values, disable them. Simply double
click the default value for the program on the right hand pane and rename the clsid value by placing a period or dash in front of it.

ie; - {b5eedee0-c06e-11cf-8c56-444553540000}

Then exit the registry, refresh, and right click a file to see if the
item was removed from the menu.

Some programs - like WinZip or WinRar - will add
several items to your right click menu but all of them will be removed by
deleting or disabling their one context menu handler.



Note that the above key only applies to the right click menu of files.

To remove entries from the right click context menu of folders, you need to
navigate to the Folder and Drive keys:



HKEY_CLASSES_ROOT\Folder\shellex\ContextMenuHandlers

HKEY_CLASSES_ROOT\Drive\shellex\ContextMenuHandlers



All you have to do is follow the same procedure as for Files - either disable
or delete items you wish to remove.

Adding Items

Adding Items to the right click menu of Files and Folders is also fairly
simple using the Registry. It just involves the creation of a few new keys for
each item you wish to add. You edit the same keys used for removing items.
Let's use Notepad as an example of an item you'd like to add to the right click
menu of all your files or folders.



For folders, go to this key:

HKEY_CLASSES_ROOT\Folder

Click the + sign next to Folder and expand it so that the Shell key is
visible. Right click the Shell key and choose New>Key and name the key
Notepad or whatever else you'd prefer (whatever the key is named is what will
appear in the right-click menu). Now right click the new key you made and
create another key named Command. Then, in the right hand pane, double click
"Default" and enter Notepad.exe as the value.

Exit the registry, refresh, and right click any folder. Notepad should now be
on the context menu.





For files, go here again:

HKEY_CLASSES_ROOT\*

Expand the * key and see if a Shell key exists. If it does exist, follow
the same procedure as for folders. If it does not exist, you'll have to create
a new Shell first. Just right click the * key and choose New>Key and name it
Shell. Then right click the Shell key and continue on the same way you did for
adding items to the right click menu of folders.

Once done, Notepad should appear as an option in the right click menu of
all your files.
