WIndows 10 🙂 otherwise nothing or linux
MSI Afterburner, stock since when I did OC it pooped in same games and did not like it
Iclue software, For RGB on everything that I have and sldo control the fans speeds and look at temps
Chrome or edge, why not 😛 always hets used more then anything.
VLC for media player
OBS for streaming/recording.
Steam and Epic
VMWare for Linux.
TightVNC for Remote desktop.
MalwareBytes, Solid anti-virus/malware program. If you have another you prefer, obviously just go with that. More than not, just have something in case you need to do a sweep.
I'd recommend 7zip over winrar, it's free, open source, doesn't bother you to buy anything ever and most importantly, works on all the same file formats.
