How to enable network mapping on a computer that belongs to a domain
abril 30, 2011


The network map feature in Windows 7 (which was introduced in Vista) is handy for finding other computers and devices on the network and getting a visual representation of them in the Network and Sharing Center. By default, network mapping is not enabled on computers that belong to Windows domains, but you can enable it via Group Policy. Here’s how:

1.- Click Start and in the search box, type gpedit.msc and press Enter to open the Local Group Policy editor.
2.- to Computer Configuration | Administrative Templates | Network | Link-Layer Topology Discovery.
3.- Double click “Turn on Mapper I/O (LLTDIO) Driver in the right pane.
4.- In the dialog box that appears, click the Enabled button.
5.- Options at the bottom left, check the box that says “Allow operation while in domain.”
6.- Click the Next Setting button at the top right.
7.- Do the same for the Turn On Responder (RSPNDR) Driver.
8.- Click OK.

Note that the gpedit.msc command only works on Windows 7 Pro, Enterprise and Ultimate, and these are the only editions that can be domain members. In a large domain, it may take a very long time to create a network map with hundreds of devices.

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 delete shadow copies

How to delete shadow copies

Shadow copies are great – this feature in Windows lets you access previous versions of your files and restore them to an earlier point in time. However, when Windows saves many previous versions, they can begin to take up a lot of space on your disk. This is especially troublesome if you’re using a modern faster (but lower capacity) solid state drive (SSD). You can delete shadow copies to free up disk space. Here’s

1.- Click Start and in the search box, type disk cleanup.
2.- Click the link that appears in the search results.
3.- Click “Files from all users on this computer.”
4.- Enter admin credentials if prompted to do so.
5.- Select the hard drive on which the shadow copies are stored if prompted (this selection will appear only if you have multiple drives).
6.- Click the More Options tab.
7.- Click System Restore and Shadow Copies, then click OK.
8.- Press the Delete key to verify that you want to delete the restore and shadow copies.

If you’re really pressed for space and don’t want Windows to make shadow copies, you can turn the feature off. See the instructions at

You can easily add the mail button to IE 9. Click the Tools menu and click Toolbars, then Customize. In the Customize Toolbar dialog box, find “Read mail” in the section labeled Available toolbar buttons on the left. Highlight it and click the Add button in the middle.

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 to selectively share media libraries between PCs
abril 3, 2011


Windows 7 makes it easy to share your media files (music, pictures, videos) between multiple computers in your home. The easiest way is to set up your home network as a Homegroup, in which case media streaming is enabled for all devices and PCs by default. But what if you don’t want to share your media with everyone, just with certain computers and devices? No worry – here’s what you need to do:
1.- In Windows Media Player, in the Player Library view, click the Stream button just to the right of the Organize menu.
2.- Click More Streaming Options.
3.- In the dialog box, you’ll see a list of devices on the local network. You can click the button to Allow All or you can Block All, or you can select Allow or Block for each individual computer or device.

After you set up media sharing on a computer, you’ll be able to play the files in its library from the other computers on your network for which you’ve allowed access. In Windows Media Player on the second computer, click Other Libraries. Just expand the list beneath the first computer’s name in the Other Libraries group and you can browse through the library, similarly to the way you browse through the media libraries on your local computer.
