Install current Windows service packs and other updates

Updates to the Windows operating system improve its performance and compatibility with applications. You can obtain Windows service packs by completing the following steps:

  1. Choose Start > Control Panel.
  2. Launch Windows Update and install all critical updates and service packs.

    Note: Windows Update is located in the System & Security section when you are viewing the Control Panel in category view.

For assistance installing service packs and other updates, contact Microsoft technical support.

If you've reinstalled an application on the Windows operating system after installing the latest Windows update, reinstall the update. Some applications install commonly used system files, overwriting the updated versions that the Windows update installs.
