Has anyone heard of the windows xp service pack 3 error? I need some information on how to fix it because it happened to me… Ugh I hate my computer … I recently reinstalled OS and I get all the updates and all is well until I receive the service pack 3 one and then bam it says there’s an error …
And now svchost.exe runs at 99 usage of pc along with like 100k memory use… Someone please help ugh…
System restore to SP2, uninstall all security software and try again??? 
What kind of error? Without a description or screenshot, it’ll be too vague to troubleshoot. M$ recommends that security software be disabled during installation. As a FYI, the best way to install SP3 is to slipstream it. I used nLite do it all of it.
Why don’t you just download a XP SP3 Torrent and stick your product key in it?
I retried and it worked 
thanks I just had to disable my security software and it worked
