Hi!
I’m having the same issue as reported in this thread https://forums.comodo.com/resolvedoutdated-issues-cis/bsod-windows-10-not-booting-cmdhlpsys-failure-t121433.0.html
I’m on Windows 10 1709 build 16299.547 and CIS premium 10.2.0.6526. Second time windows tries (forcibly) to update and i got the BSOD after a reboot so i had to revert to a system drive backup.
From the mentioned thread i would assume this issue would’ve been fixed, guess the best thing i can do is uninstall CIS, update Windows, reinstall CIS?
