How to downgrade my service pack 3 into 2

good day to everyone, is there anybody can teach how to downgrade SP3 to SP2 please...

Good question.

Great Question Alexjo22??? Are we moving back to Dos days - Smiling?

my OS windows XP was updated already to SP3 and I only have IE 7, me cannot make it to IE 8 'cos the requirements there is SP2. I can't go back to SP2 it doesn't exist in my system. errors keep on appearing when I install the IE 8 given by Microsoft. thank you for time... hope you understand what I mean...

This is the smartest thing Ive heard all day. you don't want to use service pack 3, it screws up the operating system.
And you don't want to use IE 8 either, it's ca-ca.

from the desktop click:
My computer>control panel> add remove software> (select service pack 3, it's at the end of the list) click install / uninstall
It will uninstall and return the computer to SP2, it's magic!

then download mozilla firefox its free, and it works way faster than internet explorer, even NASA has stopped using internet explorer

or use google chrome

I recommend turning off "automatic updates" or your computer will automatically update back to SP3, which is ca-ca.

my computer>control panel>security center>turn off automatic updates

then your computer will start flashing message balloons:
"your computer may be at risk-turn on automatic updates"
go to "microsoft power toys" and download the tool which allows turning off those irritating message balloons. (relief at last)

I wont use SP3 or automatic updates anymore, it screws up the computer.
