Take a breath. I do not work for Microsoft.
An average user is just fine with Windows. (This particular "problem" is cosmetic, since it doesn't affect functionality; when it reappeared, it went away on its own.)
By the way, Apple's hardware and OSes have bugs, too. If you want a simplistic and limited system, then go for it.
And watch your language.
The reason for the triangle "warning" is the state of a registry key. If you are NOT connected to the internet then the key value is set and the warning appears. The reason there are so many "solutions" is because there are many ways to reset the registry
entry, from direct mod to driver replacement to device reinstall, even a restart in some cases. Why we have to do this is the question. It does seem to be a fairly common problem based on internet threads/visits.
MOST users can function without correcting it, that is true, thank you for that!
HOWEVER...
This problem CAN bring real functional issues. I have been fighting this issue because some applications, like AutoCAD by subscription from AutoDesk, check this registry flag for internet connectivity. This program needs to "phone home" for license verification
over the internet monthly. If the flag is not set to the value "connected" then the program won't operate after a period of time. So it's more than cosmetic. I have found a work around for now, but it's far from solved.
