Can I reinstall SP2?

Microsoft Windows XP

I had a issue with many of the service items being turned off. I have
reactivated many but many items still donot work correctly. I would like to
uninstall sp2 and reinstall to put the system back in place. I lost all of
my restore points. Thanks for any help.
You can uninstall it and reinstall SP2. I have done it a few times on a
couple PCs and didn't have a problem.

Thanks for the assistance. I will start the process to recovery.
