There are some more ways in optimizing Windows XP with respect with to hardware and software which i would like to post here. Well this includes Hardware settings in the BIOS and Software settings regarding the hardware from within Windows. Well here it is :
1) BIOS Settings
Disable unused hardware devices from the BIOS like : Floppy Drive Controller, Serial Ports and Parallel Ports. Make sure to disable only those that you never use and do not screw the system.
2) Removing Device Driver for Unsed Devices:
First open command prompt and type in the following codes :
Now type the following code :
Set devmgr_show_nonpresent_devices = 1
Now the Device Manager Window will be opened. Then expand each section and you will see some devices which would be faded just like hidden files are shown. You can delete those drivers.
3) Software :
Uninstall programs which are not necessary.
4) Registry Cleaning :
Use registry cleaner softwares to keep your registry clean.
5) Windows Services :
Disable unwanted windows services. These make windows startup time consuming... But make sure you know what you are doing...
6) Antivirus :
Buy a complete Antivirus Pack which includes Antivirus, Antispyware, Antimalware.
7) Degramentation :
Defragment you disk drives regularly to get optimal disk performance.
All the best...!
