Notes

• The version numbers presented here are those found in the associated Microsoft
  Knowledge Base articles. Note that these differ somewhat from those actually
  displayed in SharePoint, which includes an additional "0", but does
  not include the last version number block. For example, version "12.0.6545.5001"
  shown above will actually be shown in SharePoint as "12.0.0.6545."
• The updates are often available separately for the x86 and x64 platforms.  Be sure to click the link, "Show hotfixes for all platforms and languages (2)," to see both before entering a check and downloading.
