  5. Follow the links in the Windows Update dialog box under More Information or Help and Support to try to fix the problem, and then try installing updates again by using Windows Update in Control Panel.

  6. If the preceding step didn't work, try the following steps.

  7. Open Windows Update by clicking the Start button Picture of the Start button. In the search box, type Update, and then, in the list of results, click Windows Update.

If you could not find an update for Windows that failed because of an error other than 800f0826, or if the problem persists after you have followed the steps above, an error in another area of the operating system might be preventing you from installing updates.
