I got the SP2 CD from Microsoft last Fri. installed it on Sat. everything is fine... but what they don't tell you is that you have to re-activate windows! So today dedcided to activate windows, but was told by MS that I had exceeded my activation codes, so I rang the MS freephone number but could not get through! So have now taken out SP2, and anyway I have a backup of XP just in case anything like this happens! Has anyone else had this problem? Also does anyone know how many activation codes we are allowed? I've had XP for 2 years, and had activated windows a couple of times after re-installing, so I got a DVD writer to backup my istallation, and have not activated windows for over 12 months. Anyway the conclusion is....don't install SP2!!!
