Woody Leonhard of Infoworld summarizes the current state of Microsoft KB 2919355, the ambiguously-titled 'Windows 8.1 Update' (not to be confused with the update _to_ Windows 8.1).
In short: Microsoft has frozen two discussion threads on KB2919355 issues (after 103 and 116 pages of comments), and updated the Knowledge Base article with workarounds for seven major errors... some of which don't work.
In last week's Patch Tuesday, Microsoft changed their deadline for this Update until June (formerly they were requiring all Windows 8.1 and Server 2012 systems worldwide to have installed the Update in order to receive new patches).
Meanwhile, if you run a WSUS server, you may notice that the package for KB291355 (last reissued for the third time on 6 May) was apparently silently reissued over the weekend with a new release date of '15 May 2014', but there's no indication of any software updates in the KB article. The article revision number, however, now stands at '21.0'. Yes, twenty-one revisions. With no changelog.
Anyone else with interesting stories about your deployment issues with this Update?
"The Windows interface is still there, except the start menu" is like saying "the new car dashboard is just like the old one, except we removed the steering wheel." I'm not going to enumerate the issues with the Win 8 UI. Hundreds, perhaps thousands, have documented the issues in forums, on Youtube, and other places. Corporate IT isn't adopting 8. In fact, they're doing everything they can to avoid rollouts. If you think at this point that there's no issue with Windows 8, nothing I write here will convince you there is a problem.
I explicitly wrote about non-UI related issue. Your reply with "Hundreds, perhaps thousands" of UI issues.
No, read my post again. Hundreds, perhaps thousands of *people* have written about issues with Windows8, not hundreds or thousands of UI issues. Perhaps it wasn't apparent in a quick reading of the post, but the subject of the sentence was "people". There are a handful of UI issues, but they're big ones. Regardless if you were writing about a non-UI related issue, your original premise of those people with SSDs will want Windows 8 is... strange, for a lack of a better term. Saying the only problem one will encounter is the lack of a start menu is glossing over several other bad UI issues, like how you get the Charm Bar to come out, how there's no way to know how to exit a full screen Metro app, control panel and search weirdness...
There is a cross button on top of metro apps, that you can click to quit. They are handled differently so they might appear in task manager. But they will be killed if a process requests the ownership of the common resource, kind of like android. In either case, if you are using metro app you are surely not complaining about desktop experience, isn't it. There are literally 0 apps I have ever used in my last 3 months of usage.
