I agree that Win10 1903 is an OS that needs a lot of work to make it better for DAW use. I also think it appreciates a lot of memory, too.
Nuieve here’s a 3hr + run of LantencyMon that maybe shows a more accurate picture of my PC. Like you, there are many things that I have turned off in Win10.
CONCLUSION
Your system appears to be suitable for handling real-time audio and other tasks without dropouts.
LatencyMon has been analyzing your system for 3:30:36 (h:mm:ss) on all processors.

SYSTEM INFORMATION
Computer name: DAW
OS version: Windows 10 , 10.0, version 1903, build: 18362 (x64)
Hardware: Z390 DESIGNARE, Gigabyte Technology Co., Ltd., Z390 DESIGNARE-CF
CPU: GenuineIntel Intel(R) Core™ i7-8700 CPU @ 3.20GHz
Logical processors: 12
Processor groups: 1
RAM: 32700 MB total
\
CPU SPEED
Reported CPU speed: 3192 MHz
Note: reported execution times may be calculated based on a fixed reported CPU speed. Disable variable speed settings like Intel Speed Step and AMD Cool N Quiet in the BIOS setup for more accurate results.
WARNING: the CPU speed that was measured is only a fraction of the CPU speed reported. Your CPUs may be throttled back due to variable speed settings and thermal issues. It is suggested that you run a utility which reports your actual CPU frequency and temperature.

MEASURED INTERRUPT TO USER PROCESS LATENCIES
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.
Highest measured interrupt to process latency (µs): 49.30
Average measured interrupt to process latency (µs): 2.555243
Highest measured interrupt to DPC latency (µs): 47.30
Average measured interrupt to DPC latency (µs): 0.879128

ISR count (execution time >=4000 µs): 0
\
REPORTED DPCs
DPC routines are part of the interrupt servicing dispatch mechanism and disable the possibility for a process to utilize the CPU while it is interrupted until the DPC has finished execution.
Highest DPC routine execution time (µs): 217.753133
Driver with highest DPC routine execution time: ntoskrnl.exe - NT Kernel & System, Microsoft Corporation
Highest reported total DPC routine time (%): 0.064355

Total time spent in DPCs (%) 0.070397
DPC count (execution time <250 µs): 16088072
DPC count (execution time 250-500 µs): 0
DPC count (execution time 500-999 µs): 0
DPC count (execution time 1000-1999 µs): 0
DPC count (execution time 2000-3999 µs): 0
DPC count (execution time >=4000 µs): 0
\
REPORTED HARD PAGEFAULTS
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.
NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.
Process with highest pagefault count: settingsynchost.exe
Total number of hard pagefaults 4016
Hard pagefault count of hardest hit process: 781
Number of processes hit: 15
