And I'm certain that I've personally encountered instances where both Documents folders had the Documents special folder icon (though I'm not sure if I've seen this on Win10, specifically)
This is just a project management failure that somehow got through, but the fact that it did seems to show major QA issues.
It should be the same exact action, just triggered by a message saying "Documents folder detected in 2 locations, click OK to copy".
But the solution to "we screwed up years ago" is definitely not "nuke one instance with no warning and don't even glance at what's there".
Another lovely one, for ages (probably still) OneDrive would purge it's local copy whenever you turned it off or uninstalled it. That was probably one of the most frustrating things that Windows has ever done to me.
Edit: Lord, can we please talk about "3D Objects" too? Who the hell got promoted for shoving that down everyone's throat in half a dozen places? Every week I get an update I have to run a regedit script to remove all the bullshit they've shoved into Explorer for absolutely no reason.
A sincere question: why are you an Insider? After the Windows 8.1 issues I'd be really gunshy about getting early anything for Windows. Are there upsides to that, or is it pretty much just a public service in the same sense as running nightly Firefox builds?
That, and honestly, they're pretty rock-solid. Other than this net adapter this thing past week, I've never had anything truly disruptive. OTOH, there've been a time or two that I was glad to be an insider because of a bugfix or feature that wasn't likely to be backported to stable.
And some misplaced desire to help? I can rationalize it with OSS, I can't really tell you why I feel some sort of responsibility to do it for Windows too.
My confusion was mostly just that I couldn't picture who would have the tech background and Windows familiarity to fix (and productively evaluate) weird or buggy releases, but was also willing to have their system destabilized without much warning. For myself, I expect I'd find being an Insider exhausting; even if I know enough to fix the issues, I don't use Windows very often and I'd feel lost whenever things changed and needed to be fixed.
Getting early OS updates sounded much higher-risk than nightly Firefox builds or something. But "it's a gaming machine" actually makes total sense - I forgot how many people have a nice Windows machine they use often, with no real need for it to be stable.
Nope, I just tested, only 1 folder gets the special icon.
You're not alone. It's been a bit reassuring that others run into these things. I figured maybe I was just "holding it wrong".
