I started using FrontPage nearly 20 years ago and I'm still using its offspring, Expression Web. Why?
I updated my little doomsday counter (sidebar right) today. It now knows about Windows 10.
I also reprogrammed it so it will run automatically for the next eight years, which is when Windows 10 extended support expires. Mainstream support for Windows 10 ends in October, 2020, a little over three years from now. Presumably, we'll know about Windows 10's successor by then.
Or perhaps we'll discover that Windows 10 has become software as a service and will continue forever.
I've never been emotionally attached to any of the PCs I've owned. This visit to the dump was tougher.
For a time I was happy with Driving Mode on my Windows 10 phone. Now I realize how superficial it is.
Serendipity kept me in the Windows Phone camp. It'll be okay.
There are now less than six months until support ends for Windows Vista.
Once support ends, Microsoft will post no further updates and this puts Vista into the same category as Windows XP - unsafe at any speed.
If you're still using Vista, your options are limited. Some PCs from the early Windows 7 days came with dual licenses for Vista and 7. If that is present on your PCs, you should make the upgrade as soon as possible.
If you are thinking about Windows 10 for your Vista PCs, plan on new installs, not upgrades.
Given the age of the PCs involved, new PCs with Windows 10 are probably a better bet.
Sometimes the Internet inspires deep dives. Here's my most recent.
