I need to run a C++ application to fetch data from Internet for real time financial data stream.
I want to configure a Windows 10 machine with minimum system service running, this machine is dedicated to run this application.
any ideas to share?

Well whatever you do you are still running Windows, which is not a real-time operating system.
|
|
|
|
|
the intention is: to tear down unimportant windows service to save more CPU power to serve my application

But it is still Windows in charge, so the basics remain the same.

"Real time" is also used by salesmen when they mean "really fast" or "really, really fast".
Warcraft simulates being realtime quite nice, but even there we have unexpected disconnects and lag. I prefer terms as fps, throughput, latency and uptime.
Doesn't sound like he needs visualization, so it's probably being stored in a realtime-database

Should I point to a similar post to my answer? 
If you want a Windows-environment to simply run software, then kiosk mode should work as already pointed out. Dunno if still applies, but might wanna check if you can RDP into those.
If you're asking if there's a bare-bone version of Win10, then the answer is, well, kind of[^]?
If you need the raw power, you'd use Linux. If you need to be technically realtime, you use a realtime OS like QNX.

Fetching data from the internet? That's gonna be a lot like milking an axe I'm afraid.
|
|
|
|
|
to be specific: I have bought real-time data service from a data vendor already.

Oh. Ok. So there's a handle stuck in the head? Can't you just swing the thing?

Agreed. Install a headless distro, compile the code, configure the service, reboot.
Any SBC would be able to run it. No need for an expensive machine.

Depending on how big is the amount of data to process a better machine could help.

If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about?
Help me to understand what I'm saying, and I'll explain it better to you
Rating helpful answers is nice, but saying thanks can be even nicer.

That's true. I stand corrected. I was a little premature (that's what she said  ) on that statement. It would depend on the work load.

You might want to clarify your definition of "real time".
For some of us that means within a few microseconds. For others it means within a few milliseconds.
IMHO when you include the terms "fetch data" and "internet" then "real time" is not even approachable.
Just sayin'

Additionally, can you query past data for any you missed or is it a matter of having only one chance to get it then it's gone?

I find a intersesting thread on this .

Real-time in manager-speak translates to roughly 10 seconds actual. 
|
|
|
|
|
for me, 5ms is good enough to cycle through my list to refresh data...
