--->How to remove recycle bin from your desktop Tip:

Open
Regedit by going to START - RUN and type Regedit and hit enter. Then you
should navigate to following entry in registry
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\
Desktop\NameSpace\{645FF040-5081-101B-9F08-00AA002F954E}
and delete it. This action should remove recycle bin from your desktop.


--->How to improve on shutdown time ? Close apps automatically &
quickly at shutdown tip:

Open Registry by going to
START-RUN and typing REGEDIT. Navigate to HKEY_CURRENT_USER\CONTROL
PANEL\DESKTOP and look for AutoEndTasks. On my computer default value is
0. Change it to 1. Thats all. Further more you can reduce the time it
takes for Windows to issue kill directive to all active/hung
applications.
In doing this only constraint that you should
make sure exists is that HungAppTimeout is greater than
WaitToKillAppTimeout. Change the values of WaitToKillAppTimeout to say
3500 (since default value for HungAppTimeout 5000 and for
WaitToKillAppTimeout is 20000)

--->Do you know you can have Virtual Desktops (like in Linux) with
PowerToys ?

If you have powertoys installed on Windows XP
Its available for free at Microsoft download webpage. It is very easy to
enable Microsoft Virtual Desktop Feature. Simply right click on the
Start Panel Bar also called TaskBar, Click on Tool Bar and select
Desktop manager.
You would see a set of 5 icons placed on the
right portion of the TAskBar. Click on number 1 to 4 to go to any of
the desktops. Now you have have four different Active Desktops.
IMPORTANT
NOTE: You may see a little degradation in performance.

Disable the balloon tips

Already irritated by the information balloons, covering the important buttons in the Start Menu? Start the registry editor and navigate to the following key:
HKEY_CURRENT_USER\Software\Microsoft\ Windows\CurrentVersion\Explorer\Advanced
change or add the DWORD-values EnableBalloonTips and ShowInfoTip, both with value 0.

Remove the low disk space warning

Probably you have seen the irritating 'low on disk space'-warning before, if your hard disk reaches full capacity. This warning message can be turned off by adding the DWORD-value NoLowDiskSpaceChecks with value 1 in the following key:
HKEY_CURRENT_USER\Software\MicroSoft\ Windows\CurrentVersion\Policies\Explorer

Activated NUM-LOCK

To automatically switch on the NUM-LOCK, change the value InitialKeyboardIndicators to 2 in the following key:
HKEY_CURRENT_USER\Control Panel\Keyboard

A faster Windows shutdown

Shutting down Windows can take a long time. You can speed this up (at your own risk) with the following tweaks in the registry key:
HKEY_CURRENT_USER\Control Panel\Desktop
Change the following String values:
AutoEndTasks=1
HungAppTimeout=4000
WaitToKillAppTimeout=4000
WaitToKillServiceTimeout=4000
(the last registry value is also present in HKLM\SYSTEM\CurrentControlSet\Control)

Fix for shutting down your computer automatically

In most cases, automatically shutting down can be fixed by installing the motherboard drivers (if not done already). If your computer still doesn't shut down correctly, try this registry tweak. Change the value PowerdownAfterShutdown to 1 in the following key:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon
