Security for Windows XP

Security for Windows XP

Don't you hate it when people mess with your computer without you knowing it? Here are two ways to prevent this, (and still be lazy): create a desktop icon to lock your computer, and password protect after the screen saver is activated. Both of these only work if you already have your computer password protected on login.

If you already have a password, skip to the next part.

To create a password, go to the control panel , then to user accounts . Click your account, and then the " change my password " button, enter the requested fields and click on " change password " and then close the window.

How to create a lock-down icon:

First, pick any icon on your desktop. Right click it and drag it to another place on the desktop. In the menu that appears select " copy. " Now we need to change the name and the target of the new shortcut. Right click this shortcut, and click " properties. " Make sure you are in the shortcut tab .

In the box labeled " target, " copy and paste this line:

%windir%\System32\rundll32.exe user32.dll,LockWorkStation

In the box labeled " Start in, " copy paste:

%windir%

To apply these changes click " apply. " Next you can change the icon. Just click the " change icon " button. If you're not already there hit the browse button and go to:

C:\WINDOWS\system32\shell32.dll

You'll find a nice selection of icons there.

Select an icon from the ones that appear in the box and click " ok. "

Now move to the general tab . The box on the top contains the name of your icon. Change it to whatever you want. I used "Fun Game" in the hope that if someone comes to the computer and it is not locked that they will click this icon, locking the computer. (This actually worked once!) After you are finished, click " apply ," and then " ok. "

To test your icon, double click it. You should be taken to something like a log on screen. Just enter the password to get back into windows, just as you left it too. This is different from actually logging off. Whenever you know you will be away for a while, just click that icon, and your computer will be safe.

How to lock down on screen saver:

Right click on your desktop in any empty space. Click " properties " in the menu that opens. Go to the screensaver tab. All you have to do now is click the box next to " On resume, password protect ." Click " apply, " and then " ok. "

Let your screen saver run, and see what happens after you move your mouse. This is good in case you leave suddenly and forget to click the icon we made earlier. Unlike hibernation, this will allow other programs, such as Kazaa or iMesh, to run in the background.

Nails and Health: Read the Signs
Did you know your nails can reveal clues to your overall health? A touch of white here, a rosy tinge there, or some rippling or bumps may be a sign of disease in the body. Problems in the liver, lungs, and heart can show up in your nails. Keep reading to learn what secrets your nails might reveal.



Pale Nails
Very pale nails are sometimes linked to aging. But they can also be a sign of serious illness, such as:
• Anemia
• Congestive heart failure
• Diabetes
• Liver disease
• Malnutrition



White Nails
If the nails are mostly white with darker rims, this can indicate liver problems, such as hepatitis. In this image, you can see the fingers are also jaundiced, another sign of liver trouble.



Yellow Nails
One of the most common causes of yellow nails is a fungal infection. As the infection worsens, the nail bed may retract, and nails may thicken and crumble. In rare cases, yellow nails can indicate a more serious condition such as severe thyroid disease or psoriasis.



Bluish Nails
Nails with a bluish tint can mean the body isn’t getting enough oxygen. This could indicate an infection in the lungs, such as pneumonia.



Rippled Nails
If the nail surface is rippled or pitted, this may be an early sign of psoriasis or inflammatory arthritis. Psoriasis is a skin condition that starts in the nails 10% of the time.



Cracked or Split Nails
Dry, brittle nails that frequently crack or split have been linked to thyroid disease. Cracking or splitting combined with a yellowish hue is more likely due to a fungal infection.



Puffy Nail Fold
If the skin around the nail appears red and puffy, this is known as inflammation of the nail fold. It may be the result of lupus or another connective tissue disorder.



Dark Lines Beneath the Nail
Dark lines beneath the nail should be investigated as soon as possible. They are sometimes caused by melanoma, the most dangerous type of skin cancer.



Gnawed Nails
Biting your nails may be nothing more than an old habit, but in some cases it’s a sign of persistent anxiety that could benefit from treatment. Nail biting or picking has also been linked to obsessive-compulsive disorder. If you can’t stop, it’s worth discussing with your doctor.



Nails Are Only Part of the Puzzle
Though nail changes accompany many conditions, these changes are rarely the first sign. And many nail abnormalities are harmless -- not everyone with white nails has hepatitis. If you’re concerned about the appearance of your nails, see a dermatologist.
