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.”

How to create a key combination to eject your optical drive
agosto 20, 2011

They say CD and DVD drives are going the way of the dinosaur soon, but in the meantime, many of us still use them – for installing software, for backing up data, for transferring data from one computer to another, for watching movies or playing music. Sure, you can eject the disc by pushing the hardware button or going through the menu, but if you’re a keyboard wizard who hates to remove your hands from the home keys, wouldn’t it be handy to have a key combo to do it? Here’s how to do

  1. Download NirCmd from Nirsoft (link at the bottom of the instructions).
  2. Right click on the desktop or in Windows Explorer and select New, then Shortcut. You need to first create a shortcut to which you can assign the key combination.
  3. In the “Location” field, type the path to where you saved the nircmd.exe file, and at the end of it, add “cdrom open , with quotes around the path, so the entry looks like this if you saved the NirCmd utility to a folder called SavedStuff on drive C and your CD drive is D: “c:SavedStuffircmd.exe” cdrom open D:
  4. Name the shortcut and put it wherever you want. You can put it on the desktop and double click it to eject the CD that way.
  5. Right click the shortcut icon and select Properties.
  6. Click the Shortcut tab.
  7. In the “Shortcut key” field, choose the key combination you want to use to eject the CD and click OK.

Here’s where you can download the free NirCmd tool, which you’ll note does more than just eject discs:

How to customize the shutdown button
agosto 13, 2011

By default, at the bottom right of the Windows 7 start menu is a button labeled “Shut down.” If you want to restart, log off, or put the computer to sleep instead, you have to click the arrow to the right and select the action from the drop-down menu. It’s not as if that takes a lot of time, but if you almost never shut the computer down and often need to log off and log back onto a different account, for example, you might want to change the button so you can do your most frequently used tasks with one click. Here’s how:

  1. Right click the Start button on the taskbar
  2. Select Properties
  3. Click the Start Menu tab
  4. Under “Power button action,” select the action that you want to be the default for the button.
  5. Click OK

  3. In the left pane, navigate to and click on User Configuration | Administrative Templates

  6. When you’re finished, click Apply and then OK

How to turn a USB thumb drive into a Windows 7 installation disk
julio 23, 2011

If you need to install Windows 7 on a computer that has no DVD drive and you don’t have a network connection to install from a shared DVD drive on another computer, you can install the OS from a USB thumb drive. Make sure it has plenty of free space for the installation files (I used a clean 32 GB drive). You will need to wipe everything on the drive so be sure to back up any data you have there to a different location. Here are the steps to follow to prepare the USB drive.

1.- the USB drive into a computer that does have a DVD drive.
Click Start and in the search box, type
and press CTRL+SHIFT+ENTER to open the command prompt with administrative
2.- At the command prompt, type
At the DISKPART> prompt, type
list disk
3.- Type
select disk
replacing with the number of the USB disk from the list of disks
create partition primary
format fs=fat32 quick
exit The above is not a typo. You need to type “exit” twice, once to exit the DISKPART utility and then again to close the command

Now you can insert the Windows 7 installation disc and copy all files to the USB drive. To use it to install Windows 7, insert it in the computer where you want to install the OS, make sure the BIOS is set to boot from the USB drive first, and boot up to begin the Windows setup process.

How to use location-aware printing
julio 16, 2011


Windows 7 has a cool new feature that lets you automatically switch the default printer when you move from one network to another (for example, when you move your laptop from your home network to your work network). Here’s how you set it up:

1.- Click Start and in the search box, type Devices
2.- Click the link for Devices and Printers (You can also get to this through the Control Panel)
3.- Select a printer and click Manage Default Printers (note that you won’t see this on desktop computers, only on mobile devices)
4.- Choose “Change my default printer when I change networks”
5.- Select a network, select the default printer you want to use when on that network and click Add
6.- Do the same for each available network (If you’re at home, you obviously will have to wait until you’re at work where the work network is available before you can set up the default printer for that one)

Now when you connect to a new network, Windows 7 will automatically switch to the default printer that you specified for

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).
