 It’s not hard to block USB ports for security reason.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UsbStor

If you are a computer geek then you can try editing your REG Keys

for better performances.

But

If you are not familiar with REG keys better not missing up

with these keys.

• Increasing System Performance

  If you have 512 megs or more of memory, you can increase system performance
  by having the core system kept in memory.

  Start Regedit
  Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management

            \DisablePagingExecutive
Set the value to be 1
Reboot the computer

• Increasing File System Caching

  To increase the amount of memory Windows will locked for I/O operations:

  Start Regedit
  Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager

         \Memory Management

Edit the key IoPageLockLimit

• Resolving Inability to Add or Remove Programs
  
  If a particular user cannot add or remove programs, there might be a simple registry edit neeed.

  Go to HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\Uninstall
  Change the DWORD NoAddRemovePrograms to 0 disable it

  4096 - 32megs of memory or less
  8192 - 32+ megs of memory
  16384 - 64+ megs of memory
  32768 - 128+ megs of memory
  65536 - 256+ megs of memory

• Increasing Graphics Performance

  By default, WindowsXP turns on a lot of shadows, fades, slides etc to menu items.
  Most simply slow down their display.

  To turn these off selectively:

  Right click on the My Computer icon
  Select Properties
  Click on the Advanced tab
  Under Performance, click on the Settings button
  To turn them all of, select Adjust for best performance
  My preference is to leave them all off except for Show shadows under mouse pointer and Show

         window contents while dragging .

• Decreasing Boot Time

  Microsoft has made available a program to analyze and decrease the time it takes to boot to WindowsXP
  The program is called BootVis

  Uncompress the file.
  Run BOOTVIS.EXE
  For a starting point, run Trace / Next Boot + Driver Delays
  This will reboot your computer and provide a benchmark
  After the reboot, BootVis will take a minute or two to show graphs of your system startup.
  Note how much time it takes for your system to load (click on the red vertical line)
  Then run Trace / Optimize System
  Re-Run the Next Boot + Drive Delays
  Note how much the time has decreased
  Mine went from approximately 33 to 25 seconds.

• Getting Rid of Unread Email Messages

  To remove the Unread Email message by user’s login names:

  Start Regedit
  For a single user: Go to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\UnreadMail
  For all users: Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\UnreadMail
  Create a DWORD key called MessageExpiryDays
  Give it a value of 0 .

• Speeding the Startup of Some CD Burner Programs
  
  If you use program other than the native WindowsXP CD Burner software,
  you might be able to increase the speed that it loads.

  Go to Control Panel / Administrative Tools / Services
  Double-click on IMAPI CD-Burning COM Service
  For the Startup Type, select Disabled
  Click on the OK button and then close the Services window
  If you dont You should notice .

• No GUI Boot

  If you don’t need to see the XP boot logo,

  Run MSCONFIG
  Click on the BOOT.INI tab
  Check the box for /NOGUIBOOT .

• Clearing the Page File on Shutdown

  Click on the Start button
  Go to the Control Panel
  Administrative Tools
  Local Security Policy
  Local Policies
  Click on Security Options
  Right hand menu - right click on "Shutdown: Clear Virtual Memory Pagefile"
  Select "Enable"
  Reboot

  For regedit users…..
  If you want to clear the page file on each shutdown:

  Start Regedit
  Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management

\ClearPageFileAtShutdown
Set the value to 1 .

• Not Displaying Logon, Logoff, Startup and Shutdown Status Messages
  
  To turn these off:

  Start Regedit
  Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies

\system
If it is not already there, create a DWORD value named DisableStatusMessages
Give it a value of 1 .

• Cleaning the Prefetch Directory

  WindowsXP has a new feature called Prefetch. This keeps a shortcut to recently used programs.
  However it can fill up with old and obsolete programs.

  To clean this periodically go to:

  Star / Run / Prefetch
  Press Ctrl-A to highlight all the shorcuts
  Delete them .

• Services You Can Disable
  
  There are quite a few services you can disable from starting automatically.
  This would be to speed up your boot time and free resources.
  They are only suggestions so I suggestion you read the description of each one when you run Services
  and that you turn them off one at a time.

  Some possibilities are:
  Alerter
  Application Management
  Clipbook
  Fast UserSwitching
  Human Interface Devices
  Indexing Service
  Messenger
  Net Logon
  NetMeeting
  QOS RSVP
  Remote Desktop Help Session Manager
  Remote Registry
  Routing & Remote Access
  SSDP Discovery Service
  Universal Plug and Play Device Host
  Web Client .

Good Luck.

CONNECTING 2 MONITORS ON LAPTOP…..

Mirrored mode and Extended Desktop mode
You can use one of two modes to project your desktop on a projector screen:
•
Mirrored mode: In this mode, your desktop (or screen) is duplicated on the projector screen, so your audience sees what’s on your screen. For example, use Mirrored mode if you’re recording ideas as people mention them during a brainstorming session and you want participants to see what’s being recorded. The main downside of this mode is that instant message pop-ups, e-mail notifications, and other potentially annoying messages appear on the screen and interrupt the presentation. Also, if you browse for a file or switch between programs, your audience will see these actions on the projector screen, which may be disruptive or make your presentation appear unpolished.
•
Extended Desktop mode: In this mode, you extend your mobile PC screen space by using an additional display (whether a monitor or a projector screen). You can then use each screen independently. This mode is well suited for presentations because you can display the slides on one screen (usually the projector), and then hide notifications and other miscellaneous messages, and complete other tasks, such as taking notes, on your mobile PC screen. This mode is also very useful when you want to extend your workspace while using your mobile PC at your desk.
Project a presentation in Mirrored mode
The steps that you follow to use Mirrored mode and display your mobile PC desktop on a projector depend on the hardware and software settings that are defined by the computer manufacturer. To project your mobile PC screen in Mirrored mode, you will need to either click an icon in the notification area in the bottom right of the screen or pressing a function key combination (usually FUNCTION+F5 or FUNCTION+F8).

Using multiple monitors at your desk
Mobile PCs are great productivity tools and excellent entertainment devices, but they are not ideal for extended use. Most mobile PC screens are too small to read text comfortably for an extended period of time, and many mobile PCs also lack a full-size keyboard or a mouse, which can aggravate your hands if you use them all day.
You can address these shortcomings by using Extended Desktop to use both your mobile PC screen and an external monitor to increase screen space.
Set up a second monitor
Before you perform the steps below, plug the secondary monitor into the external VGA port of your mobile PC and then place your mobile PC (the primary monitor) close to the secondary monitor to ensure swifter navigation between screens.
1.
Right-click the desktop of your mobile PC, and then click Properties on the shortcut menu.
2.
In the Display Properties dialog box, on the Settings tab, click the blue rectangle with the number 2 (which represents the external monitor), and then select the Extend my Windows desktop onto this monitor check box.
3.
Under Screen resolution, drag the slider to the right to change the screen resolution of Monitor 2 to 1024 by 768 pixels, and then click OK.

You can change the screen resolution in the Display Properties dialog box.
4.
When prompted, click Yes.
Note: If your desktop background does not appear on the external monitor, click No, and then repeat step 3 to decrease the screen resolution.
Adjust the position of the monitors
By default, Windows places the second screen to the right of the first (or primary) one. You can change the position of the monitors to reflect their physical position.
1.
Right-click the desktop of your mobile PC, and then click Properties on the shortcut menu.
2.
In the Display Properties dialog box, on the Settings tab, drag the graphical representation of Monitor 2 (the blue box with the number 2 in it) to the left of Monitor 1, and then click OK.
3.
When prompted, click Yes.
Adjust your screen settings
When you first enable Extended Desktop mode, your taskbar and any icons on your desktop appear on the mobile PC screen; desktop space without icons appears on the external monitor. You may find it easier to show the taskbar on the external monitor since it is usually the larger of the two screens.
1.
On your mobile PC screen, right-click an empty area of the taskbar, and then click Lock the Taskbar.
2.
Drag the taskbar to the external desktop and drop it where you want it to appear.
You can now take advantage of the extra screen space by dragging program windows to the external monitor. You can also resize windows to stretch across the two screens.
By taking advantage of additional monitors, you can share information with others more effectively when you’re giving a presentation and also improve your productivity by extending your workspace when you’re using your mobile PC at your desk
