XP hides some system software you might want to remove, such as Windows Messenger, but you can tickle it and make it disgorge everything.
Using Notepad or Edit, edit the text file /windows/inf/sysoc.inf, search for the word 'hide' and remove it.
You can then go to the Add or Remove Programs in the Control Panel, select Add/Remove Windows Components and there will be your prey, exposed and vulnerable.

Creating a desktop shortcut for locking your computer
If you use your computer in an area where others may have access to it, and there are things on your system you would rather have kept confidential, locking your desktop when you leave the computer is an essential task.
Here's a recipe for a desktop shortcut that will lock your computer in two easy clicks:
Right click on an empty area of the desktop and choose 'new' then 'shortcut.' The create shortcut wizard will open; in the first text box,
type '%windir%\System32\rundll32.exe user32.dll,LockWorkStation' and then give your shortcut an appropriate name on the next page, and hit 'finish.'
You will notice that the shortcut you created has a blank icon. To select a more appropriate one, right click on the shortcut and hit 'properties.' In the 'shortcut' tab, click the 'change icon' button.
In the 'look for icons in this file' box, type '%SystemRoot%\system32\SHELL32.dll' then click 'ok' to see a range of icons for your new shortcut. Choose an appropriate icon. Your desktop locking shortcut is now ready for use. Test it out. It is useful if u have an account as it will prompt 4 a password.

NETWORK TROUBLESHOOTING
TROUBLESHOOTING OF N.I.C CARDSN.I.C Not Sensing:
First, check for the dust on the pin of the connector. If any, clean it to ensure proper contact of the tracks. (Or cleaning solution).
If that does not solve the problem, check the crystal frequency. If it is not working, replace the crystal.
If the crystal is O.K, check if the S.M.D or any components are dry soldered. If so, resolder the components.
If that doesn’t work them replace the S.M.D. This will definitely solve the problem.
No Display If The Card Is Inserted:
Just check for the shorting on the card, because display will not come if there is any shorting. If a shorting is found, try to correct it.
If any component is shorted, try replacing the component. This will solve your problem.
N.I.C Not Connecting Through BNC As Well As UTP:
Check for any dry soldering of the components on the card. If any, resolder the same.
Check the transceivers on the card. If they are faulty, replace them with working ones.
Check for shorting of the S.M.D. Correct it, if any.
Touch up the S.M.D, in case it is dry- soldered.
Replace the main S.M.D.
N.I.C Not Connecting Through UTP Only:
In the case of the UTP, the path for the data is from the S.M.D to the transceiver & then to the cable.
Therefore, if the UTP is not working, the problem lies mainly with the transceiver. Try changing the transceiver.
If the Transceiver is O.K, try changing the delay line.
N.I.C Not Connecting Through BNC Only:
In the case of the BNC, the path for the data is from the S.M.D to the voltage converter, converter to the transceiver & then to the cable.
So, if the BNC is not working, check whether the converter is giving the proper output voltage. If it is faulty, replace it.
If the converter output is correct, then the transceiver could be faulty. Try changing the same.
If that does not help, the problem lies with the S.M.D alone. Replace it.

TROUBLESHOOTING IN MOTHERBOARD
The motherboard faults are the most challenging ones. Diagnosing its faults requires great patience. However, 80% of the problem can be detected using the DIAG CARD. But it would only give you an idea of which signal is missing accordingly to which the actual problem has to be traced out. Some of the basic faults found in motherboards are:
No Display:
The board is physically checked for any damaged. Any physically damaged parts are replaced with new ones.
Check the 3V battery. If low, replace the battery.
In cases the problem is due to improper CMOS setting, clear the CMOS with the help of the CLEAR CMOS jumper.
Check to ensure that the jumpers pertaining to CPU speed (i.e. base frequency & multiplication factor) are correct as incorrect settings may result in over clocking of the speed.
As the first step, the existing BIOS is changed with a reference working one & the board is re-checked. If the problem was with the bios, it will be solved. The original BIOS is re-programmed.
If the BIOS is not a problem, the main controller IC is checked for shorting of pins & for any physically damage. The shorting, if any, must be removed.
If the main controller IC is dry-soldered, it should be touched up.
Lastly, if the board is not working, the main controller IC is replaced. This will definitely solve the problem.
Continuous Reset High:
The reset signal on the board remains continuously high because +5V is not coming on the reset pin. Due to this, the clock & the other signals are not generated.
Firstly, the voltages on the reset pins of the external connector are checked.
One pin has to have +5V& the other ground.
Mostly the +5V pin carries less voltage. In this case, an external wire jumper is connected from pin b3 of the slot to the pin. Connecting the wire jumper solves the problem in most of the cases.
If this does not solve the problem, we check the voltages of the different regulators on the board. If any one is found fault
