Typically we wait for
"Most corporate enterprises have yet to migrate to Windows 11 – typically they wait for..."
We don't just wait for 18 months, we spend about two years hammering on the idiots until they release a version we can stomach. That starts in the preview builds, continues past launch day, apology day, update broke my computer day, and and continues until a minimally functional build arrives.
That usually takes about 2 years, starting from the preview builds a few months before launch, as people's ears poke up and more sites that arent' early adopters take their first serious look at the new potato baby.
Sometime they fail to release a viable version, and people just stay on the previous solid one until the apology edition arrives. That happened after both XP and windows 7, so there is no reason to expect 11 is special. They fix it or we wait them out. They have to blink before the business world does, they are locked into support contracts and they need the revenue more than their customers need an unreliable OS that will kill productivity.
The funny thing is that it is the same design by committee and flawed market research that has wrecked every major OS release since, what, windows 2000 probably? They broke XP at launch and it had to be fixed, and win 7 stole market share from the trainwreck that proceeded it almost immediately, but lulling market share off XP took enough years it was more about people buying new computers than upgrades.
And it's the same mistakes, time after time. UI changes that aren't a meaningful improvement but are enough to leave users totally lost. Important settings and tools move or are missing. New UI chrome that changes how all the apps look, and so sloppily implemented that have the controls still have to be dug up off some old version of the pull down menu, which is probably hidden by default. Hidden controls that only render on the UI when you hover over them, controls that slide around onscreen as the pointer moves. Profoundly and obviously dumb choices that the community howls at the moment it hit's the previews.
Yet the one part of the process they refuse to talk about fixing is the one that drives all these mistakes. The people doing the market research for them are expensive, implementing features people hate costs money, as does fixing or removing them, and those mistakes add up. Because of the collective insanity that stuck the PC world post tablet, they reversed the direction of mouse controls to make them more consistent with devices that don't use mice, even on machines that don't have touchscreens. Now they have to support a control to change the scrolling behavior for every device till the end of time. Regardless of what that defaults to people a large fraction of people will hate it, and it will ruin the critical honeymoon period to win people over to a new OS build. Same for hiding file extensions on an OS that still decides how to handle a file primarily based on it's file extensions. So in a mixed shop you have people making office docs on Mas that could care less about the extension and sending them to people who can't see them by default, and can't fix them without changing the default settings.
