I installed a new hard drive in my Compaq laptop and did Windows XP install wth the restore disks. After the restore, I was able to use Windows Update to get all the updates that were available but didnt get SP 3. But since then whenever I go to get updates , the updates show up but it always shows the download size at 0kb and when I click on install, the installation window pops up and then it says"the following updates were not installed" but no error messages. ive never seen this before. Thanks
