Setting up a new mode of password in ur PC

Higly Risk :

 Open Run and type cmd and hit enter....

Now type SYSKEY ...

If XP,

It will ask like ok, cancel, update....

press UPDATE...

 After that click Password Startup radio button...

Two text boxes with password and  confirm will be enabled... type the desired password and confirm that password again...

If VISTA & 7

Its just a single step more... in the begining it will ask for administration approval... Just give CONTINUE... thats it... and remaining the same steps...

 NOTE: Guys if u forgot this password there is no way to reset or change it... u need to format ur OPERATING SYSTEM... 

To prevent ur system u can use this... But u need to be aware of ur password... Because there is no way to crack this password...

Need of this password:

• Bios password can be resetted or removed by removing CMOS or jumper....
• user loggin password can be resetted or removed by inserting a cd named PASSWORD RESETTER.. 

DO U THINK U HAVE ANY OTHER OPTION TO SET SOME SECUTITY FOR UR PC???
