Comodo firewall often prevents the shutdown of my computer (Windows XP Home SP3)

I like this firewall software. But there is a problem with the shutdown. I’ve searched for a solution in this forum. But maybe someone could give me special hints. If there isn’t a solution I can’t use this software in the future.

Maybe your user profile registry hive isn’t unloading properly.

You could give the User Profile Hive Cleanup Service a try.
