Good morning, COMODO Firewall keeps blocking this "Windows operating system". I checked the rules but it has one to allow all requests! What should I do? Thanks in advance. I tried to unlock the application but, after few second, it blocks it again

In Windows Updater applications one is missing. But I didn't edit the rules by myself. It's in file groups under file rating.
Is this the famous disappearing rule bug?

About the missing file, it is because i have a 64-bit Windows and you are maybe using 32-bit. I have no idea, you might try to repair Comodo Firewall. But if your real problem is other than not being able to access the internet, i don't think ARP blocking is a problem. Unless DHCP doesn't work and you don't have set manually IP address.
I also have this in my logs.

If I let the ARP on, there will be issues or not? I don't see any problem when using my PC, just all these requests blocked

Assuming you have firewall at reasonable settings, you can probably solve the problem by putting firewall in learning mode for a couple reboots.

I know this is an old thread, but the issue is still very relevant.
There is an interesting discussion about it on the Comodo forum:

CIS - Firewall blocks the "Windows Operating System" in Windows 10. - Firewall Help - CIS

CIS - Firewall blocks the "Windows Operating System" in Windows 10. - Firewall Help - CIS
forums.comodo.com
The main point I understood from the discussion over there is that in most cases, this is not a cause for worry. Sometimes, a network connection gets "fragmented" and Comodo firewall blocks it for security reasons.

Yeah, this is an old thread. I do no longer use COMODO on my systems because I prefer to harden windows with registry tweaks (it doesn't affect the performance of my computer), however I remeber that when ARP was enabled it was continously blocking these kind of requests on a clean system. I read the thread on COMODO forums and I also had the problem of being unable to use WPA2 enterprise networks with ARP enabled
