If your computer is running Windows 7, this is the last year Microsoft will support it with security updates. But some critics say that's like a car company saying you need to buy a new car because they'll no longer fix your old one.
Tech writer John Quain is hopping mad at the way Microsoft treats its customers.
"I just think it's appalling; I'm kind of shocked. Like I said, if you take that car analogy, that's just not a way that companies do business."
He says nearly half of U.S. businesses still run Windows 7.
"I'm surprised there isn't more pushback from bigger customers to say 'hey, you can't just pull the plug after an arbitrary number of years because you think you want people to upgrade to Windows 10.'"
Microsoft says Windows 7's life will come to an end in January. But Quain says about 40% of consumer PCs are still running 7 and most consumers say, if it ain't broke, don't fix it.
"I think what most people do is they wait until they really need a new laptop or new desktop, a new computer in the back office. Until that happens there's no real reason to change and go through all the headaches and heartaches of trying to upgrade to a new operating system."
Quain says there's no benefit to 10 that requires an update from 7 -- other than the end of support for 7, which will be eleven years old in 2020.
