I have noticed that after installing SP3 on 3 of my computers, the computer will freeze up for a long period of time...
Just now, I decided to reformat and reinstall XP on two of my PC's and applied SP3, and it happened again... I did this format/reinstall just to make sure the freeze was not caused by a virus infection or other problems. On my laptop, however, I did not apply SP3 after I reinstalled the OS... and it never froze...
Can anyone, who had the chance to install SP3, confirm that this is true?
