Now weighing in at Version 19.0, KB 2952664 is a “compatibility update” to ease upgrading from Windows 7 to Windows 10. The analogous patch for Windows 8.1,KB 2976978, is now up to version 22.0, and the patch for Windows 7 without SP 1,KB 2977759, stands at version 18.0.
All three have been re-released six times in the past three months. I talked about them on March 2, the last time they came out the Update chute.
