Unable to install Windows Update

In Windows XP sometimes users get problems in installing windows updates. This is a problem of a corrupted file called IUCTL.dll

  3. Go to Program files
  4. Display all hidden file and folders

  6. Delete all content inside it except the V4 folder
  7. Now open V4 folder and delete all the content except iuhist.xml
  8. Start run and type
  9. Restart Windows regsvr32 /u C:\WINNT\System32\IUCTL.dll
  10. Done
