I do have both Internet, and InternetCustom templates (along with: Automatic, Compat, Datacenter, DatacenterCustom) in Windows 10 Pro when listing them with PowerShell.
Trying to change CongestionProvider in PowerShell gives a "Read Only" error, so I use netsh to change the congestion provider (but not the template), and it was changing those "00000000" and "04000000" values in the "..\26" key, as in:
In Windows 8, there was a way to change the CongestionProvider to CTCP in the following key ("...\0" instead of "...\26"):

I don't remember exactly which pair, but likely the "02" is the congestion algorithm. This key also exists in Windows 10, not sure if/when it is used.
