Hi
I did update to 8.1 but I had issues with the sound that I could't solve.
The sound is very important to me because I do a lot of video editing.
I use Malwarebytes, Windows Defender and the native Windows firewall along with SuperAntiSpyware.
I have had problems with Windows Explorer on Windows 8 since I first installed it, on my previous computer.
When I got my new computer it had the same issues, so I just use Chrome.
When I did upgrade to 8.1 I still had the same problems with IE.
My Comcast Home Page isn't the only page that won't load and I've found other people having the same issues.
I have no idea why.
A lot of people reported problems with sound in Windows 8, I don't know it they have been fixed or not.
It was very weird, because some sounds on the same file would be distorted while others would not.
All voice file were distorted.
I haven't found any issues with AdBlocker so far, and it does really work.
Mike
