I figured out how to easy change wcp.dll.
(This allows installing latest CU's, on PRO version)

0. Install KB4132216.
1. Get NSudo, ProcessHacker, or other utility that allows you to run software with TrustedInstaller rights/access.
2. Run with it file manager/explorer (in my case Explorer++)
3. Navigate to - C:\Windows\WinSxS\amd64_microsoft-windows-servicingstack_31bf3856ad364e35_10.0.14393.0_none_36d3ccc3ddfd1ecb
4. Copy wcp.dll
5. Paste copied file in - C:\Windows\WinSxS\amd64_microsoft-windows-servicingstack_31bf3856ad364e35_10.0.14393.2272_none_7f1843c421e0830a
This folder should appear when you install KB4132216. (if necessary create backup, and replace wcp file)
6. Install latest cumulatives.
*I think folder names can change for other users, but it should be easy to understand 14393.0 and 14393.2272, where to take file, and where to paste it.

Tested on 2018-12 CU (KB4483229), installed without problems.
Before update system had only 2018-05 CU (KB4103720).

@TEMPUSER221218 - a follow up on this: the May 2019 (aka 2019-05) & newer cumulative updates (CUs) starting with KB4494440 may not work with this method (and will fail install prematurely in Windows) as you will need to use a newer wcp.dll file like 14393.2182 from KB4093137 SSU. any older build of the wcp.dll file (like 14393.0) will not work with recent CUs as they depend on newer wcp.dll files like the .2182 or higher version.

KB4494440 & newer (like the June 2019 CU - KB4503267) will say the "not applicable" message unless you have either KB4498947 or KB4503537 SSU installed - I tested this on a Win10 v1607 Enterprise edition (a non-ltsb version) which went out of support in April 2019 [the KB4493473 CU from 4/2019 was the last update that worked w/out needing to use an older wcp.dll file]. KB4494440 & newer will not install 100% on the education & enterprise versions of Win10 v1607 but will install 100% successfully on LTSB 2016 edition only (and on x86/32bit v1607 on devices with Intel Cloverview/Clover Trail CPUs)

Copy 14383.2182 of the wcp.dll file onto either the "14393.2963" or "14393.3022" WinSXS folder first, then try to install a recent CU from 2019-05 & later.
