Have you ever wondered why you have to press ALT + CLT + DEL every time you login to you favorite Windows PC or Laptop? The significance of ALT + CLT + DEL is that it protects the login password in case of an intrusion or a malicious attack. At the time of login, when you press ALT + CLT + DEL, the system redirects you to an authentic login screen. In fact the kernel is the only one which has the authority to redirect the ALT + CLT + DEL buttons to login screen. No program running on windows can use or assign these keys as shortcut commands to open a program.
Every time when you logon to your windows device (Laptop or PC), on pressing these keys you will be redirected to the authentic login page. Imagine if your Windows device is vulnerable to a malicious code or an intrusion attack, then the Windows login screen may be mimicked, and a same virtual page could be created down as that of login page. If this happens, hackers can redirect you to this fake login screen, instead of the original login screen. If this happens then, when you enter the password on this fake login screen, believing it to be authentic, your password could be stolen and could be used for allsorts of illegal things. Your device could then be under the hacker’s control, and all your files could be accessed or modified without your knowledge.
In brief significance of ALT + CLT + DEL is to secure your windows login password, and help protect your content. However it is to be noted that ALT + CLT + DEL can only protect your machine from fake login screens. It does not find any application in protecting your files from various attacks once your are logged in to your devices. It is a simple method of redirecting the user to the original login page. An equivalent security check is also used by Linux operating System which uses ALT + CLT + Pause for redirecting the users to login page.
If you are sure about the security of your files, you can disable the option to surpass ALT + CLT + DEL security check for faster booting. For Windows Vista, Windows 7 and Windows 8 users it is very easy to surpass this feature.
FOR WINDOWS VISTA, WINDOWS 7 AND WINDOWS 8 USERS
- Open RUN. Start Menu > type “RUN” ; OR Press Win+R keys from anywhere
- Type “Control Userpasswords2”
- Click on the “Advanced Tab”.
- Check OR Uncheck the option “Require User to press ALT + CLT + Delete”.
FOR WINDOWS XP USERS
The steps mentioned in the above tutorial for Windows 7 users is applicable for Windows XP users too. In addition to the above mentioned steps, users will have to un-check the option Change the ways users log on or off. This option is checked by default, and if you do not uncheck this option, you will never get the ALT + CLT + DEL sequence before login, even if you follow the above procedure.
This option can be un-checked from: Start>>Control Panel>> User Accounts>>Change the ways users log on or off.
