Hey @commandery11
Compared to Windows, conventional bloatware is rarely a problem on Linux and even less so on Linux ARM systems.
Slowness and hanging/crashing on a Raspberry Pi is typically attributed to running out of RAM used by your standard applications. The Pi 3 is limited to 1 GB so it’s hard to fit a browser and games. You can run top to monitor the amount of memory or for something easier to read try htop:
sudo apt install htop
If you need to kill a particular process before it overtakes your system, use the killall command.
