Today's the day countless PC's will be able to upgrade, free-of-charge, to Microsoft's latest version of Windows. But will anybody do it?

FOX News Radio's Eben Brown reports for FOX On Tech:

Upgrading to Windows 10 today? Microsoft gives it away free to users of Windows 7 and 8.

(Laff) "They need it to be free to get people to really look at it. And just because it's free doesn't mean people are going to use it, but I think it will get more eyeballs."

Tech entrepreneur Steven Laff of afarsitebetter.com says Windows in general has suffered in popularity.

(Laff) "They need acceptance. They still have a bunch of ATM's all around the country, as well as the military, still using Windows XP."

And the hope is Windows 10 will win back disappointed users who never liked Windows 8.

(Laff) "There was no 'Start' button, and that confused a lot of people."

It'll feature Cortana, Microsoft's much-praised digital assistant. And even a new machine won't cost as much as a Mac.

(Laff) "You know, they say, 'Oh, Macs are so expensive'. But you think about the undeserved, shall we say, or those who have less money to spend on a computer. They deserve a machine they can use effectively and efficiently, just like anybody else."
