Can network type reset when working?

Today I was working for a couple of hours without any problems on my Windows 8.1 Pro 64-bit, processing many files and saving them over my network folders.

Suddenly, at one point, when I was about to save a file over a network folder, the system asked me whether I want to turn file sharing and network discovery on.

Hmmm... I believe I had set it up many weeks ago right after system installation and haven't touched it since then. I've also noticed that my LAN network status was somehow changed to "Public" (the same happened to my Kaspersky Internet Security firewall settings related to networks, but as far as I know it reads those information from the system settings).

Can such things happen like that? I know it is possible to manually change network type and turn on/off files sharing and network discovery but I haven't do so for sure. I don't thing there's a hotkey combination that does so and I could select it accidentally. Thus, I believe the system might have changed / reseted it by itself, but... it's simply odd.

Most likely Kasperksy got amnesia. Possible that it updated, which caused this. I really do not see a need to use a firewall on your personal LAN, when behind a NAT or decent router with good firewall rules. It is really overkill on a personal LAN, to use a product like this. Now if the unit is going to be used off of the LAN. Then yes by all means use the Firewall, when on Public networks.

Thanks for this information.

I used to disable Windows firewall right after installation of a third-party internet security software, but I had to turn it back on because of some application demand. Unfortunately I can't remember what it was, however I has problems with installation and support told me that it need Windows Firewall running for proper functioning. I might be wrong but something in my head tells me it was the driver for HP wireless printer, though I can't guarantee that.

Nothing should be telling you to turn the firewall back on, if it is disabled.
