Today is your luck dear my dear friend. I have decided to share a few tricks I know in Windows XP. Are you ready for an adventure? Ok follow me!!
1. Total Uptime2. Lock XP
You can lock your XP workstation with two clicks of the mouse. Create a new shortcut on your desktop using a right-click button on the mouse, and enter 'rundll32.exe user32.dll,LockWorkStation' in the location field. Give the shortcut a name you like "lockme or shutup or anything to help you remember". That's it -- just double click on it and your computer will be locked. And if that's not easy enough, Windows key + L will do the same.
3. SAFE MODE
Sometimes when troubleshooting a Windows XP problem, you need to enter Safe Mode. Typically, you would press the F8 key during the boot process to enter Windows XP Safe Mode but that can be very difficult in some cases depending on the problem you're having.
This simple tip will get you into the Windows XP Safe Mode a whole lot easier using the System Configuration Utility, sometimes called "msconfig".
Here's How:

4. System Administration
Most cases when your windows operating system is too slow to access the control panel or you have been hit by a virus that keeps you from doing any administrative tasks or you just want a shortcut to perform a system core task at hand. Windows has a system configuration utility that allows editing of your system in a few easy steps
1. Click start and then run
2. In the text box in the Run window, type msconfig and click OK. This will open the System Configuration Utility program.
3. On top of the system configuration utility you have the following tabs
- General
- System
- Win
- Boot
- Services
- Startup
- Tools 
- Whatever is listed above can help you to do a lot of systems administration from the way it starts and behaves to shutdown.
