Win XP Won't Completely Shutdown

It should now successfully complete the Shut Down process.

Performance Increase Through My Computer

Easy enough tweak to usually find out about it on your own, but still, some of us
still don't find it right away. So here it is:
•Start > right-click on My Computer and select Properties.
•Click on the "Advanced" tab.
•See the "Performance" section? Click "Settings".
•Disable the following:

Fade or slide menus into view
Fade or slide ToolTips into view
Fade out menu items after clicking
Show Shadows under menus
Slide open combo boxes
Slide taskbar buttons
Use a background image for each folder type
Use common tasks in folders
There, now Windows will still look nice and perform faster.

Deal with System Hang at Startup

If your system hangs about 2 or 3 minutes at startup, where you can't access the Start
button or the Taskbar, it may be due to one specific service (Background Intelligent
Transfer) running in the background. Microsoft put out a patch for this but it didn't
work for me.
Here's what you do:
•Click on Start/Run, type 'msconfig', then click 'OK'.
•Go to the 'Services' tab, find the 'Background Intelligent Transfer' service.
•Disable it, apply the changes & reboot.

How to Shutdown XP Faster??

Like previous versions of windows, it takes long time to restart or shutdown windows
XP when the "Exit Windows" sound is enabled.
To solve this problem you must disable this useless sound.

•Click Start button.

•Go to settings > Control Panel > Sound, Speech and Audio devices > Sounds and Audio
Devices > Sounds.

•Then under program events and windows menu click on "Exit Windows" sub-menu and
highlight it. Now from sounds you can select, choose "none" and then click Apply and
OK.

Now you should see some improvements when shutting down your system.

Pop a banner each time Windows Boots

Well I use this trick to pop a religious message when ever I boot up my system. you can also use it as a reminder too.


To pop a banner which can contain any message you want to display just before a user is going to log on, go to the key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\
CurrentVersion\WinLogon

Now create a new string Value in the right pane named LegalNoticeCaption and enter the value that you want to see in the Menu Bar. Now create yet another new string value and name it: LegalNoticeText. Modify it and insert the message you want to display each time Windows boots. This can be effectively used to display the company's private policy each time the user logs on to his NT box. It's .reg file would be:

REGEDIT4
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\
CurrentVersion\Winlogon]
"LegalNoticeCaption"="Caption here."
