I had to set up an old Lenovo desktop which has native drivers only for Windows Vista and 7. I can't get Windows 10 or 8.1 running on it so I have to keep 7. I want to know whether most 3rd party apps, especially Chrome and Google Drive, will be supported on it after its end of life next year or will it be dysfunctional?
Will apps like Chrome and Adobe Reader continue to be supported on Windows 7 after its end of life?
Like with XP they will most likely be supported for a time. How long there's no way of knowing.
Yes, but. Eventually it will stop. I estimate about 4 years…
They should, for a good few years.
"Windows 7" and "Windows 10" are (or were) both windows version 6.x internally.
There's no fundamental reason any general programs written for Win 10 should not also be compatible with Win 7, other that the authors or Microsoft being deliberately awkward.
[Win 10 is now numbered as V10 but that happened after its first release].
Most major programs should stop supporting Windows 7 about 2-3 years after its end of life. It is strongly recommended that you upgrade to a modern operating system such as Windows 8.1 or Windows 10.
For a while, but eventually they would require Windows 8 or 10 to run. If that ends up being the case you could stick with whatever version is the last to run on it.
I see You mentioned 2 of Google's own apps & 1 that's actually mostly supported with plugins for most modern browsers anyway.
The Google Chrome & Google Drive apps are both easy - and I believe the newest Chrome or Chromium will handle most features of Adobe Reader.
Although I personally use a bootable USB flashdrive OS for all modern hardware projects & most streaming websites, I was considering the freeware situation of the Chrome OS for a while, because they offered it as a free (although complicated) upgrade for most older computers to convert to.
This would solve both app needs for You plus again, I berilieve the Adobe Reader situation can be addressed with a browser plugin, or that Chrome itself handles them natively.
I personally scrapped the idea of the Chrome upgrades because of a few reasons - I currently have (am storing in My living space, really) about 8 different systems from between the XP & Vista days / P4 & dual-core class systems, but all different brands.
And the 2nd reason was because of the heavily online-based funxctionalities of the Chromebooks / OS. I had heard of the same idea with a linux core being done, & done very well, with an OS called "Peppermint", & the installation & setup plus the simpler hardware management system in it would've been more effective. But I also don't use online-based OS types on a system, I personally use Puppy linux OFTEN.
And Puppy's getting better & better every time I screw around with My configs, running on the Slackware & Ubuntu linux kernels.
