Microsoft has made many versions of Windows.
They put out Windows Updates to fix the bugs in the systems.
Then they put out a new version for hundreds of $$$s.
Then put out Windows Updates, etc., etc. .
They do things this way to keep making money.
If they just put out one version & supplied free Windows Updates, they would make no money except from sales of computers with the OS already installed.
This goes back to the dealings with IBM.
Read up on that if you wish.
Bill knew there was more money in software than hardware.
He was shrewed.
I have been rambling a bit.
The point I am thinking about is the Free upgrade thing with Windows 8.1 & possibly Windows 9.
This is a major change in corporate strategy.
This is a good move.
It will enhance public opinion about Microsoft in a positive manner.
Whether they are doing this out of the kindness of their very rich heart or not, it will help people with little money.
Maybe they figure they have made enough Billions$$$ they can afford to be nice to their customers.
I'm through speculating.(& ranting)
