Daily product hacking tips and tricks

For my next trick I will make a user account disappear, yet remain a full functioning account. Today's Security Tip is another way to lock down your system, and it does this by hiding specified user accounts. This feature is only available in XP and 2000, so unfortunately the rest of you are out of luck. This process does involve an easy registry edit, but if you're uncomfortable with that you might want to think twice about attempting this.

Normally when you log into XP, you see the startup screen where you see all the icons for the users who can access. What this tip does is allow you to hide a desired account from this screen. If you want to log on as this user you have to press Cntrl+Alt+Del twice at the Welcome screen to make a Windows Security dialog box appear. Here you can type in the user name and password of the hidden account and log in. Limited Users shouldn't be able to see any sign of you except for the listing in the Documents and Settings folder. Other administrative users will be able to see your hidden account in Control Panel/User Accounts, so keep this in mind when you're planning this out.
All right, now down to the good stuff. If having a hidden account sounds like your cup of tea, and you have no problem with small Registry augmentation, then let's go:
* First we need to open up the Registry Editor. Go to Start/Run and type "regedit" and click OK
* You should be looking at the Registry editor, and what we need to do now is navigate to H-KEY\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\SpecialAccounts\Userlist . You will not see this folder if you do not have "show hidden system files" turned on.
* Once here we need to create another DWORD value. This is easier than it sounds, right click on the User list label file on the left side of the screen and select New>DWORD . You'll see the new entry in the right pane of the window, rename this value the name of the user account you want hidden (exactly how it is listed in the Startup screen, case sensitive) and leave the value at 0.
* Close your Registry Editor and restart the PC. When the Welcome screen comes up you'll notice that there's no icon for the user you just concealed. So how do you log in? This is where you press Cntrl+Alt+Del 2x's and the Windows Security Dialog box will come asking you to authenticate (name/password) after this the system should log you in.
Here's one more thing you might want to keep in mind, Windows logon screen. This is the screen where you see the available users you can choose to log in as. You can turn this option on/off in the User Accounts ( Start/Control Panel/User Accounts then "Change the way Users log in or off" and "Use Windows Welcome Screen" and you need to turn it off if you plan on using a hidden account and there are no other accounts on the system. The reason why is that the Windows doesn't have any user accounts to display in the Welcome screen, so it will continuously reboot. Now if you do run into this or any problems simply enter Safe mode at the next boot, this will allow you to go to the User Accounts Window and fix any problems. If you find that you can't log in at all with your hidden account go back and look at the registry value you created. Make sure you're spelling the user name is correct and that it's in the right location in the registry.

Many computers take a lot of time to boot (or start ).This is due to many reasons.

Some slight changes can do wonders for your system:

1.Press start->run then type msconfig and press enter.

Go to the startup tab. Here you will see a list of startup items. These are all the programs that automatically start when you boot your PC. It is these that slow down the boot up process.

So uncheck all the unwanted items like ms-office, messengers other utilities that u may not need at startup). Don't uncheck your antivirus software.

Restart your Pc to and see for yourself, your pc will now boot faster....

2.A great new feature in Microsoft Windows XP is the ability to do a boot defragment. This places all boot files next to each other on the disk to allow for faster booting. By default this option is enabled, but on some systems it is not, so below is the information on how to turn it on:

Go to Start Menu and Click Run
Type in regedit then click ok
Find "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Dfrg\BootOpt imizeFunction"
Select "Enable" from the list on the right
Right on it and select "Modify"
Change the value to Y .
Reboot your Pc and see the change yourself.

3.SPEED UP BOOT BY DISABLING UNUSED PORTS.!!

You may have tried many tweaks like modifying windows XP start-up applications, prefetches, unload DLLs method, etc. And yes those methods do work for me.
I have just accidentally found out another way to give you an extra boost in windows XP's boot performance. This is done by disabling your unused devices in
Device Manager. for example, if you don't have input devices that are connected to one of your USB's or COM ports, disabling them will give you an extra performance boost in booting. Go to Control Panel -> System -> Hardware tab -> device manager Disable devices that you don't use for your PC and then restart.
