Part 1: What Is Build 14393.970?

4. April 2017 & “2021” in your request

You also mentioned 2021. This could mean:

  • You want to compare with April 2021 updates (build 20348 – Windows Server 2022, not 2016)
  • Or you want to see how the April 2017 build looks from a 2021 perspective (end of support, patching history)

By 2021, Windows Server 2016 (LTSC 1607) had:

  • Mainstream support ended: January 11, 2022 (but in 2021 it was still active)
  • Latest build in 2021: ~14393.4585 (by late 2021)

So April 2017 build (14393.970) was already very outdated by 2021 standards.

8. If you actually meant build 14393.970 (April 2017) vs 2021 state

By 2021, to secure this build you would need hundreds of subsequent cumulative updates. Running 14393.970 in 2021 would leave the server vulnerable to:

  • CVE-2020-1472 (Zerologon)
  • CVE-2021-1678 (Spooler)
  • CVE-2021-26414 (DCOM)
  • Many others
