Hang on a sec - what your saying is old unsupported devices - such as a 4 year old Windows Vista 7 laptop have a best version. So why, JUST NOW, right when win8 is around the corner are the automatic updates which are enabled on every new PC restricting my dad's functionality?

This isn't a case of his installed the latest win8 beta (he has not surprisingly as he was in IT for 30 years - but it's in a separate boot partition and runs all of his usb functions perfectly). This is an update to vista 32 bit drivers which has lessoned his functionally roughly a month before win8 comes out.

Could be a bug, could be a coincidence. Could be microsoft are shaking the tree just enough to make people question if they need the new OS.

Lets take a couple more points of view - you've probably seen the start trek TNG vs special edition videos where the original footage looked WAY worse than what was aired originally. If not maybe your a gamer? Notice how blizzard are preparing "Titan" for launch (new mmo) whilst at the same time releasing a kung-fu panda expansion for wow whilst addressing none of the failings Guild Wars 2 has highlighted.

It pays for companies to make their old products look obsolete whilst retaining their brand loyalty

Sorry for rant - had a few to drink.

Since the update introduced an unwelcome new feature and you had to roll back, you're kinda supporting my point actually : Every old unsupported device has one "best" version, and it's not always the newest one.

Microsoft say Oct 26 for Win 8, but you'd have to look at the machine specs to see if an upgrade is possible. The interface changes haven't been welcomed by all, either.

Quite a few people hold back on new windows releases until the teething issues have been ironed out... so win 7 is looking good at this point.

You say that but I was round at my dads today and he'd had to roll back his Vista laptop to an earlier backup because the latest "updates" meant it no longer had the USB resources to run both his printer and scanner. When's Win 8 out again?
