Honestly, I don't know wtf you are doing

Are you saying that if you close e.g. the Windows Reader app (or some other one, like Weather, or Calendar, or Kindle), then it doesn't show in Task Manager afterwards?

Nope, still shows up however it did prevent me from deleting a pdf as you said it did for you.

I've reciently switched to Windows 8.1. At first I liked it, but after using it for a while I realise it's not very stable.

Firstly, hibernation is very buggy and crashes if you don't set it up correctly.

Secondly, there is a horrible memory allocation bug when playing games on integrated graphics: http://answers.microsoft.com/en-us/windows/forum/windows8_1-gaming/your-computer-is-low-on-memory-when-its-clearly/6fd6d158-1835-4179-b09f-975ea65e4281

Windows 8.1 does have some weird bugs with games. A Starcraft 2 crash managed to garble up my Winsock beyond repair. Had some fun times with that one.

This would drive me up the wall. Unless I'm installing a mod or playing an otherwise power-user-savvy game (e.g. Dwarf Fortress), my brain pretty much completely shuts off in gaming mode. I'd like to keep it that way.

Having never used Windows 8 in a serious capacity, I don't have much input to give to this discussion, but it does seem to have made some major strides in 8.1.

I had to use it. Mandatory for Visual Studio 2013 and developing games for Windows Phone 8. First thing I install is Classic Shell.

Yeah, VS 2013 looks quite nice, and is pretty much the principal thing getting me to consider upgrading.

As I've said, deleting the file is not the problem. That's a petty symptom, not the cause (or problem). Maybe it occurs once in 1000 or so, I wouldn't know (I can only tell I saw this happen once last week, and haven't tried to reproduce it actively). Whether it accidentially works for you or whether it works most of the time but only accidentially fails (maybe even only fails on my computer because of some other constellations which interact?) is unimportant.

What matters is that Windows 8 is being dishonest about what it is doing. You tell it "Close that program" and it replies "Yeah sure, OK (fuck you, I'll do what I want!)".

Of course you never notice that you've been lied to, unless you look in Task Manager, or unless such a locked file issue (or another issue) randomly pops up. Or unless you maybe get a "this computer doesn't have enough RAM" error, which I've had once under Windows 8 too. With no programs running, mind you.

I've just had the dubious pleasure of using the UI without a mouse (i.e keyboard-only, no touchscreen, no mouse). This was a development machine running Server 2012 and acting as a Hyper-V host, and I was troubleshooting some hardware-related issues on it. It was certainly an .... interesting .... experience.
