It'll depend on which version of Windows 10 you're updated to (as mentioned
below). I suppose a system could fall behind updates if not connected to
the Internet; that's easy enough to fix. With Microsoft's suggested
configuration,
even a very drifty system RTC won't get very far off.
Why hesitate to install something that helps you and those your trying to
communicate with.
If Windows is already offering the level of service you need, there's
no need to add third-party software that may not offer the same level of
service or not receive the same level of support. Nice to avoid the additional
complexity, and, in the case of some third-party software, potential security
risk.
Anyway, Microsoft has documented how to configure Windows 10 for highly
accurate time with no additional software required. Seems like a pretty good
bargain to me.

This strikes me as perhaps dated with respect to Windows 10.
My Win 10 Pro box here (1809, 17763.134) runs the default Windows Time Service,
always has - configured to 'set time automatically'. Every now and again I'll
look at
time.is and it'll say I'm within 15mS. I just powered-up a Windows 10 Home
notebook
that has been powered-down a while; it was off 2 minutes, but I did a manual
'Internet Time Sync' and it seems to tracking well (I suspect it might have been
skewing back on-time and I kicked the process along).
[I did select time.nist.gov as my time server on one system, but
time.windows.com
seems functionally as good]
Note that Windows 10 (version 1607 or later) documentation says:
"Time synchronization in Windows 10 and Windows Server 2016 has been substantially improved. Under reasonable operating
conditions, systems can be configured to maintain 1ms (millisecond) accuracy or better (with respect to UTC)."
