Show adminstrator account at Windows XP logon screen

When you install Windows XP on your PC, a default administrator account named ‘Administrator’ is created. This account is visible on the login screen when you boot Windows XP. But when you create any other account having administrator rights, the default ‘Administrator’ account is not shown on the login screen. If you want it to show on the login screen, follow these steps:

Open the registry editor by clicking on Start menu >Run, and typing ‘regedit’
The registry editor opens up. Go to HKEY_LOCAL_MACHINE\Microsoft\WindowsNT\CurrentVersion\Winlogon\SpecialAccounts\UserList. Double click the Administrator and change its value data to ‘1’. If Administrator is not there, right click in the right pane and select New>DWORD. Name it Administrator and put its value data as 1. That’s it. The next time you boot your PC, you will find the administrator account along with your personal account in the logon screen.

Enable network adaptor’s onboard processor

If you have a network card and it has got its own onboard processor, you can take off the load of network processing from your CPU. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters and create a new DWORD by right clicking on the right hand side pane of the registry editor and selecting new>DWORD. Name it as “DisableTaskOffload”. Set its value to 0 to enable offloading network processing onto the network card. You will have to restart Windows for this to take effect.

Disable Shutdown in Windows XP

It’s maddening when someone is working on your PC and shuts down and shuts it down mistakenly or mischievously (whatever may be the case!) even after telling him/her a hundred times not to do so. Imagine if you can disable the shut down itself! (Off course, you can pull out the power plug though!) But if you really want to disable your shutdown in your PC, follow these steps: 

Navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer. In the right hand pane right click on a blank space and select New> DWORD Value and call it “NoClose”. Set its value to 1 to disable shutting down your PC.
