Remove Startup Scripts in XP

Startup scripts are programs that are set to start whenever the computer boots up. By accessing the startup menu settings, you can decide what programs you want to allow to start when the computer starts and which ones you don’t.
This System Configuration panel is easy to access, but unless you know exactly what script you want to disable on startup, you shouldn’t use it without consulting a professional, lest you accidentally damage the operating system, rendering it inoperable.
Instructions
1.Press the “Start” button, click the “Run” option and type in “MSCONFIG” and then hit the Enter key.
2.Click the “Startup” tab and scroll through the list of startup programs and scripts until you find the startup script that you wish to remove from the list.
3.Uncheck the checkbox next to the name of the script you’re removing and then click the “Apply” button. Click the “OK” button and then choose whether to restart the computer immediately or wait until later. You must restart the computer in order to apply the settings you have selected.

What Is 64-Bit OS?

A 64-bit operating system is one that can process information in 64 bits instead of the smaller, standard 32 bits. A 64-bit operating system is available for modern computers, and it can improve the speed of a machine as long as the machine supports it.

Advantage
The 64-bit operating system refers to the amount of information the processor can handle concurrently. A 64-bit processor can process 64 bits of ones and zeros at the same time. A 32-bit processor can only process 32 ones and zeros at a time, which makes it slower.
Requirements
To install a 64-bit operating system, your processor needs enough memory to handle the amount of information. It works best if you have large amounts of random access memory (RAM).
Considerations
64-bit operating systems require 64-bit drivers for the computer. Therefore, when upgrading, you must download a 64-bit driver from the manufacturer.
Software
32-bit software can be run on a computer running a 64-bit operating system. However, software developed specifically for a 64-bit machine is not backward compatible.
Operating Systems
Microsoft Windows is compatible with 32-bit and 64-bit operating systems. Mac and Linux also support 64-bit architectures.
