Well, a little over two weeks of using this as my Main OS, and it's finally starting to show some signs of instability.
The basic desktop, and GUI, and Explorer, and other basic file management and interface functions all seem to be solid ; but when I'm gaming, the W8 has started to sometimes just switch off ; not crash, but it simply turns the computer off.
And it also seems that the extremely poorly implemented audio management policies that Microsoft created during development of Longhorn are still present in W8 ; as they are in Vista, 2k8, and W7. The drivers most likely to break down during any work session of the Longhorn generation of Windows are the audio drivers ; and the drivers most likely to cause lagging and stuttering in the graphics interface or during gaming etc are the audio drivers.
Except it's not really the drivers, it's the audio implementation policy that was devised by Microsoft and whichever individual partner (can't remember which), that the vast majority of audio hardware manufacturers were not invited to contribute towards during the design phase of Longhorn, which even so many years later continues to cause stability problems...
I have certainly witnessed both GUI lag and stuttering of this kind in W8 with simultaneous audio systems failure (not actually preventing audio playback though).
Adding to these woes, my stupid neighbour's chronic vandalism with the electricity here, by regularly overcharging the circuit breaker from using his electric barbecue and so on, have caused some damage to my internet router which is now working at 25% downstream capacity
(it's less of a mystery to me now how his own computer system can be in such a dismally poor shape), so that potentially some of the problems I'm now having could be due to damaged data on my hard drives
--- the instability I refer to and the audio problems are not directly related to this electrical maniac IMO, but the strange shutdowns might be...
