21H1 very old? Hmmm you say tomato I say tomoto. I get it, MS want's everyone in the cloud so the credit card meter is always on and if they could flip a switch today it would likely be that way for everyone. But then I suspect many wouldn't bite into that apple, they'd simply go somewhere else. Don't get me wrong, I've been with "MS only products" for 43 years and have no plans to change. But MS behaves as if money is no object, unless of course it requires them to pony up on making good to claims they've made, then it's a different story.
21H1 not supported any longer? If it's not supported, then why does MS track installations and licensing or provide upgrades that are pushed your system without getting consent from the person who's paid for the license and owns the hardware? When it blows up as it so often does, it's not MS's time that gets wasted. So, it looks to me like it's being supported, if not why bother with such details? Are there anymore oxymoronic comments you'd like to make?
I'm slow to upgrade because MS quality control has really slipped backwards over the last 10 years. It's become very difficult to get a stable platform, if you're an IT developer, until something has been out there for about 3 years. Developers need stable bits, not something where the goal line is constantly moving. This includes the long-term support cycle they've implemented. There's nothing bad about improving products, I agree with many that MS is world renowned for their innovative solutions, but they really fall short when it comes to documentation and quality control.
Example, I got a popup last week saying an upgrade to SQL Server Mgt Studio was available, so I clicked on it. Now I am rebuilding my SQL server from scratch. It didn't just change SSMS, it screwed up bits for SQL Server because MS doesn't do enough testing before releasing. So, forgive me but, until that changes, upgrading more often than not is a disaster rather than a benefit. And as I said, I've been doing this since 1981 and its exactly why I normally keep WSUS up and running, just so I can prevent these kinds of disasters. But this one slipped through because MS doesn't believe customers should have any choice, other than how much money to spend.
It's been a long time since I've posted here and asked for help, but I was curious to see if I would get some real help or that old you need to upgrade answer, and sure enough. You'd think MS would recognize when that old dog just won't hunt any longer. And trying to force it only drives customers to competitors.
Thanks for your suggestions I always appreciate help, I'll give it a try and we'll see if MS support is as good as they think it is.
