How to shut your computer down automatically at the same time every day
septiembre 3, 2011

Want to make sure your Windows 7 computer shuts down at the same time every day (or night) without having to go through the shutdown process manually? All you have to do is create a scheduled task. Here’s how:

  1. Click the Start button and in the search box, type Scheduled tasks
  2. Click the item when it appears in the search results list under “Control Panel.”
  3. In the Task Scheduler console, in the Actions pane on the right, click “Create Basic Task …”.
  4. In the Wizard page that opens, give the task a name such as “Shutdown” and write a description (if you want) such as “Shuts down the computer at 1:00 a.m. every day.”
  5. Click Next.
  6. On the Task Trigger page, select “Daily” and click Next.
  7. On the Start Date and Time page, fill in the date and time you want to begin (such as 9/10/11 and 1:00 a.m.) and click Next.
  8. On the Action page, click “Start a Program” and click Next.
  9. On the Start a Program page, in the Program/script field, type:
  10. C:WindowsSystem32shutdown.exe
  11. Windows is installed on a drive other than C, substitute that drive letter.
  12. Click Next.
  13. Review the Summary page and click Finish.
  14. Now Windows will automatically shut down at 1:00 a.m. each day. You’ll get a pop-up notification telling you, before it does so, that “Windows will shut down in less than a minute.”

  3. In the left pane, navigate to and click on User Configuration | Administrative Templates
  4. In the right pane, double click the folder name “Ctrl+Alt+Del Options”
  5. In the right pane, you’ll see the items that you can remove (for example, “Remove Lock Computer”). To remove one, double click it and click Enabled to enable the policy and remove the item from the screen menu
  6. When you’re finished, click Apply and then OK

To see the change, press CTRL+ALT+DEL

How to change the listening port for Remote Desktop connections
julio 2, 2011


As some readers noted in response to last week’s editorial about Windows 7 Remote Desktop, you can increase security by changing the default port through which RDP connects (normally port 3389). Here’s how:

1.- Open your registry editor and navigate to the following location:
2.- HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Control \ TerminalServer \ WinStations \ RDP-Tcp\PortNumber
3.- Click Edit | Modify
4.- In the properties box, click Decimal
5.- Type in the new port number that you want to use (should be a port not in use by any other protocol)
6.- Click OK
7.- Close the registry editor and reboot the computer to apply the change

To connect via Remote Desktop over the Internet to a computer on a non-default port, when you enter the computer name in the Remote Desktop Connection client, add a colon and the port number (for example: Computername:3390).

How to retrieve a forgotten security key for your wi-fi network
abril 23, 2011


I recently got email from a reader who asked if there is any way to find out the security key for his home wi-fi network. He set up the network over a year ago and configured his computers to connect to it, and has been using it ever since. Now he has a new laptop that he wants to connect to the wireless network but he’s forgotten the key. Luckily, if you already have another Windows 7 computer that connects to the network, there is a way to retrieve the key. Here’s how:

1.- Go to the wi-fi enabled computer that’s connected to the network.
2.- In the notification area (system tray), click the Network icon.
3.- Right click the name of the wi-fi network and select Properties.
4.- Click the Security tab.
5.- Check the “Show Characters” checkbox.

This will display the key.

How can I bypass the administrator password?
abril 16, 2011


Help! My friend’s father is recently deceased and she needs to access his computer to pay his bills and find out about his financial information that he kept on the computer. No one else knows his password or an administrator password to change permissions so nobody can get into the operating system (Windows 7 Professional). Is there any way to do this? Thanks! – Evan K.

You may be able to use Offline NT Password & Registry Editor (which, despite the name, also works with Windows 2000, XP, Vista and Windows 7) to remove the password from the admin account and log on. It’s a bootable program that you download as an .ISO file on another computer and burn to a CD. Then you can boot the father’s computer from the CD. You don’t have to know the username; it will list the accounts that exist on the system. It’s a free download and you can get it here:

How to make a program always start in administrator mode
abril 10, 2011


There are some programs, especially tools and utilities, that need to run in administrator mode in order to do what they’re intended to do. You can navigate to the executable file, right click it and select to run as administrator each time you want to run it, but that’s a bit of a hassle. Instead, you can create a shortcut that you can use to open the program in admin mode every time. Here’s

1.- First, make a shortcut on your desktop or in another location. Right click an empty space on the desktop and click New and then Shortcut.
2.- In the Create Shortcut wizard, browse to the location of the executable file and click Next.
3.- Give the shortcut a name and then click Finish.
4.- Now right click the shortcut and select Properties.
5.- Click the Advanced button.
6.- Check the box that says “Run as administrator” and click OK.

Now just double click the shortcut to start the program and it will automatically run in administrator mode.

How do I use Remote Desktop over the Internet with a dynamic IP address?
febrero 5, 2011


Sometimes, I’d like to be able to access my desktop when I’m on the road, but I have no idea how to even get started using remote desktop. I’m on Comcast’s broadband, so I have a dynamic IP. Plus, my desktop is behind the Comcast router, a D-link router, and then a Linksys router. How in the world would I ever know how to get through to my computer?

If you could, please provide a link to a few articles that will help me get started using Remote Desktop. – Joe M.


Remote Desktop is a great tool for accessing another computer and viewing and controlling its desktop over the network. On a local network, no problem. It’s as simple as enabling the RD service on the host computer and entering that host’s information in the Remote Desktop Connection client program on the client computer. But you’re right – when you’re going over the Internet, you need a public IP to connect to.

There are a few different solutions. One is to use something like LogMeIn Hamachi, which creates a VPN through which you can Remote Desktop to the Hamachi address. Here’s a link:

Another service you can use to assign a fully qualified domain name to your dynamic IP address and detect and automatically change the address when you’re assigned a new one is:

Hope this helps!
