Should I Enable Core Isolation on My 2020 HP Laptop?

Core Isolation is mainly a security feature, and for many older devices, it isn't essential. If your laptop keeps rebooting, it might not be related to Core Isolation. You mentioned that it’s a regular restart and not a BSOD, so it might be worth looking at other potential causes like driver issues or system updates.

Turning Core Isolation off could help if it's causing conflict with your older hardware. But before making changes, check if your drivers are up to date, as compatibility could be a bigger factor in those random reboots.
