Is Comodo that block Windows, maybe the firewall as well.
I’m back using Comodo CIS now that Windows as been upgraded but how you can say use only the Firewall will not lock Windows from upgrading? Maybe is the Firewall to lock Windows files.
I hope the Comodo team can take care of this, in different years I never seen this issue resolved and it’s sad.
I have also to say that the stable version of CIS get the unistaller corrupted so was not possible Unistall CIS. For be able to do I must download the new CIS annunced here so once was re-installed I was able to unistall CIS.
