HTC ONE APP Disabling
As a rule,if you can disable an app,it shouldn't* have any ill effects on other apps.
It's actually a nice compromise of having the option,as you can't really hurt anything.
*If you do see some undesirable effects,just work backward from the previous apps that you disabled until everything is running as desired once again.
EDIT: Just to clarify,we are speaking only of disabling apps,not deletion of apps,on a stock un-rooted phone.
