I had to put something in the internet world where my solution is available to everyone.
In hindsight yes, the solution is simple. most solutions are.
Can I share just some insight if you don't mind - I had been searching everything and nothing was working and no one presented any real solutions. They all said, run troubleshooter, try this, try that.. nothing worked.
And caveat - no guarantee this will work for you. But... it did work for me, so here it is:
Run CCleaner.
The software is free.
The version I used was v5.26.5937 (64-bit)
I know your concerned, that maybe this issue is a virus or malware.. all of those are possibilities.
For me, the internet would generally work fine after a restart for a while then it would just lose connectivity, meanwhile my internet worked fine with everything else.
If I had to guess it's some kind of malware just messing with your browsers ability to communicate with the internet. Seemly hamrless.. Most malware appears that way at first.
So CCleaner cleans all the BS out.. for the most part. I just cleaned everything, scanned, analyzed... did registry cleaner etc.
Then voila` didn't even have to do a restart, my browser that was not working... started working fine again!
ALTERNATE SOLUTIONS:
Restart Computer - this should temporarily enable your browser use so that you can download MOZILLA FIREFOX (or an alternative browser other than the one that is failing you). I have read somewhere that Chrome has a bug where their blackout program causes browsers to fail.
(basically try a different browser other than the one that is failing).
IF THE ABOVE DOESN'T SOLVE CONTINE:
Move those files to an drive seperate from your computer.
Restart your computer.
The simple act of removing the files which may or may not include malware may elimnate the issue; thus Restoring is not required.
If the problem persists then you've already prepared your computer for restoration. There are a few options available. To access this menu. Click on the start button, hold shift and click on restart (while holding shift). Your computer will reboot with options for troubleshooting, restoring to a previous save point, etc.
