Trouble disabling Windows Firewall & connection issues

Windows 8

Since my last post here (https://forums.comodo.com/install-setup-configuration-help-cis/error-1603-other-issues-t96164.0.html), I refreshed my OS, reinstalled Comodo, and everything seemed to be working fine for about a week. Today, however, I was unable to connect to the internet. Troubleshooting leads me to “Ethernet doesn’t have a valid IP configuration”. So I tried using the wireless adapter instead. Same error, but with Wifi. Using the ethernet cable allows me to connect using other devices. I noticed I’m being given a local IP of 169.xxx.xxx.xxx, and that’s a problem. I tried running some command prompt lines that were suggested in threads elsewhere for similar issues, renewing ip, I can’t remember the exact commands off the top of my head, but it didn’t help. I tried using System Restore to roll back two days, but after an hour of my system trying to do that, it rebooted saying there was some kind of failure in the restore process and my files have not been restored.

Somewhere in here, I went into the Action Center hoping to stumble across some solution, and while the Action Center in the taskbar was reporting no issues, I noticed that Windows Firewall had (in)conveniently turned itself back on without my permission. So I disabled it, still running CIS. I also noticed that Network Discovery and File and Printer Sharing, which I also disabled before, had managed to turn themselves back on. So I disabled them. An hour later or so, still trying to fix my connection issues, I checked the Action Center again, and found that Windows Firewall had turned itself back on, again, as well as turning back on Network Discovery and File and Printer Sharing. (Shouldn’t UAC, which I have cranked up to max, prevent these things from changing themselves without the user’s permission?)

Everything was working fine yesterday, everything else on the network appears to be working fine, and no programs were recently installed on the computer in question.

I’ve been a lifelong Windows user, but 8 has given me just as much time troubleshooting problems as it has functioning as it’s suppose to. I’m so tempted to just sink that time into learning Ubuntu or something else instead. :-\

UPDATE
So I tried an earlier System Restore point, and it worked, and it fixed the problem with my internet connection. Doesn’t make me feel good that that’s the solution, seeing as how SR’s failed on me on a number of occasions in the last couple of months. I also figured out what was causing the Firewall/File Sharing problem. Disabling File Sharing enables the Windows Firewall. Disabling the Windows Firewall enables File and Printer Sharing and Network Discovery. I don’t use file or printer sharing, and it has security and privacy concerns if it’s left enabled Is there some way I can kill both poisons on this system at the same time?

Unrelated: How would I figure out if my hardware is compatible and has all of the necessary drivers to install Ubuntu?

Windows 8 has been a pain in the ......■■■■ This Is a solution that I use (A permanent solution, but you may or may not like it)

First, hit the “windows” button and the “r” button
type in “services.msc”
In services, look for “windows firewall” and double click on it
At “startup” click on it and choose “disable”
Now under service statue click on “stop”
Click on “apply”
Now "click on “ok”
***optional, but since your already at services, If you like you might as well disable “windows defender” from starting up. ***** :wink:

Next find “network connections” somewhere in windows 8, I can’t tell you where it’s located because I use “classic shell” (so I can get the start button and start menu back) and I disabled the metro screen" It ■■■■■■ me off one too many times

From network connections,
Right click on “ethernet or local area connection or wifi” it doesn’t matter
click on “properties”
Under “networking” untick the File and Printer Sharing and then click on “uninstall” Remember if you do uninstall it, remember first that I don’t know how to reinstall it, if you change your mind later. I never reinstalled mine because I never had a reason to learn how before.

I'm so tempted to just sink that time into learning Ubuntu or something else instead.
If your interested, look up on how upgrade windows 8 (Although microsoft calls it downgrading LOL..) It's basicly comes down to downloading all the needed drivers first like video, lan wireless audio drivers) first and saving it to a extrenal harddrive. Disabling "secureboot" and if you like convert gpt to mbr. It's a little bit more to it then that, but thats bacisly it ;)

Just an idea :-La
