you can always reinstall them from microsoft should something go wrong, but im fairly sure none of those will simply cause your computer to stop working should they be removed (as they mostly deal with the software with games)
i have gone through this process already and deleted all of the C++ files but none have helped my issue.
for the future though, if you are unsure about what can be deleted safely, there are multiple sites that can tell you if its ok to delete it. but if you want to know for sure, VMware is a program you can download which is basically like running a computer from your computer, like a simulation almost. just install it, figure out what you want to run from it and how much space to use, and tamper with all the files on that. if that crashes it wont damage your computer in any way.
back to the topic though, my ticket is still open but i keep getting the same copy paste teir 1 "im sorry we have done everything, contact a professional" i hope someone like a community manager or someone who actually gives a shit about their own game reads this because im SO close to just saying ❤ ❤ ❤ ❤ it and back charging everything i ever bought NCsoft related. nothing screams bad customer service like only giving copy paste layer 8 issues then after 4-5 tries say well we cant help you, good luck.
seriously never thought a a gaming company as large as this would A not only not have live support, but also how they never escalate any issues which are FOR SURE damaging for the game.
