For those of you checking out the Store and deciding to click on that banner for the 8.1 upgrade go to the PC manufacturers website and search out your model and see if it is on their 8.1 approved list. I'm seeing to many people not checking and end up having
me roll back their PC to 8.0. I've see anywhere from BlueScreens to noscreens, continuous reboots and or dead systems along with networking problems. You may have the latest drivers but they may not be 8.1 certified. If your system is ready your 8.1 will come
as a normal upgrade and I've seen no problems on those systems yet (crossed fingers).
And on those that did the Store update to 8.1 I've tried all the above fixes and none of them worked. All three major browsers failed even though networking devices say they were running fine. Actually Firefox got me on the internet to google but choked
up and started failing after a few web sites, IE and Chrome failed to connect right off the bat.
