Disable a user from logging off Windows

In order to make sure that a user always shuts down the Windows instead of logging off, you can disable the logging off options from the Windows. By disabling the logging off options, a user can either switch the user, or will have to shut down the system. He/she will not be able to log off the system, but will be able to shutdown the system.

In order to remove the logging off option from the Window, you'll have to remove the "Log Off" from the start menu and from the Task Manager as well.

1. Remove Log Off option from Task Manager

In order to remove the "log off " menu option from the Task Manager's menu, do as follows:

  1. Open Group Policy Editor (Start->Run->"gpedit.msc")
  2. On the left go to, User Configuration->Administrative Templates->System->Ctrl+Alt+Del Options.
  3. On the right, Enable this setting "Remove Logoff". (see figure below)

This setting does not let the user log off the system by using any method, including programs run from the command line, such as scripts. It also disables or removes all menu items and buttons that log the user off the system except from the Start Menu.

2. Remove Log Off from the Start Menu

To remove the log off button from the Start Menu, do as follows:

  1. Open Group Policy Editor (Start->Run->"gpedit.msc")
  2. On the left go to, User Configuration->Administrative Templates->Start Menu and Taskbar.
  3. On the right, Enable this setting "Remove Logoff on the Start Menu". (see figure below)
If you enable this setting, the Log Off item does not appear in the Start menu. This setting also removes the Display Logoff item from Start Menu Options. As a result, users cannot restore the Log Off item to the Start Menu.

Copy from Command Prompt & paste to Clipboard EASILY

It's a pain if you need to copy some text from the Windows XP command prompt and save it in clipboard or any other text editor such as Notepad. You'll need to use the command prompt system menu's edit menu and use the mark and copy commands.

A better alternative is to use the clip command utility available from Windows Server 2003. This command line utility also works in Windows XP Pro. All you need to do is copy the clip.EXE from Windows\System32 folder from Windows 2003 system and paste it in Windows\System32 folder.

What if you don't have access to Windows 2003 system? In that case you can download the clip.EXE from here.

Clip.EXE Usage

In order to use you can use the pipe (|) from the command line and clip command. For example, If you want to copy the folder listing into the clipboard, simply type

dir | clip

in the command line and the folder listing will be copied to the clipboard. Now all you got to do is paste in it Notepad or anywhere else. Sweet and Simple.

Note: It also works in Windows XP Home & Windows Vista (Business).

New form of Image verification is coming soon

Image verification process is not new to netters. The irritating, ugly distorted texts may be history soon. Microsoft is researching on the Image verification technology (also called 'Human Interactive Proofs'). The problem with the existing technology is that, it is getting old and hackers are starting to tweak their codes to fool the HIPs.

So, how the future HIP may look? May be like this:


Yes, you may be asked to identify the object. Cats and dogs will be appearing in online registration forms soon.

Again, hackers may soon find a way to by-pass this kitten technique (!?!) if the system doesn't have enough number of images to rotate (may be a million)

The research is not going to end there. They may be showing us small video clips as HIP!
