A nice explanation of Core Isolation: https://feedthecuriosity.com/windows-os/what-is-core-isolation-and-memory-integrity-in-windows-11/ Attention: it only works on a 'modern device'. I saw that you also use OSArmor. That program is compatible with Core Isolation. Why are you still running W. 7? Would the risk of a (since January 14, 2020) not supported OS be compensated by SpyShelter and OSArmor? I highly doubt.
