System is running fine, UI partly not consistent

I have Windows 8 Pro x64 now for about 3 months in operation and am very happy, but I was also with Windows. 7
During normal operations you will notice no difference, a few windows are distributed over the monitors whether behind now Windows 7 or 8 sitting, makes no difference.
So where are the changes? There are mostly little things that delight me here.
- Reasonable multimonitor support, taskbar, you can now stretch across all monitors and displays the window in the taskbar of the appropriate monitor. Wallpaper can be selected for each screen.
- ISOs can mount without any additional software.
- The Task Manager shows much more, but so often we do not look in there, yes.
- Performance seems to me better, but on a SSD go most tasks so quickly from equip that a few percents are completely irrelevant.
- Copy and move operations have a fancy display and can be sidelined.
- If one calls his own a touch screen, some parts of the GUIs are suitable exactly for it.
- The Windows Security Essentials are already integrated in the Defender -> no other virus protection necessary.
- Simple, somewhat angular and elegant design white to please in any case.
- In the comments I was also made to file versioning and storage pools, with which one can combine multiple drives together, so that the data is replicated on all disks / mirrored. (Similar to RAID 1)

But what is now with the new Metro / Modern / Windows UI? Well, I remember in the normal operation of hardly anything.
But it's there and it most clearly falls on the Start menu. The Start menu is now all over the screen, makes a difference? No, at least not for me. Folders, programs or anything else can be still anpinnen and search there too. When searching also has done, it is now for programs, settings, files, and all apps that support it (eg, Mail, Calendar, Bing, ...) categorized. This brings order, but also has a disadvantage compared to Windows 7:
I want to edit the settings of the mouse in Windows 7, so I go to the keyboard, press the Windows key, type in "Mouse" and press Enter. Unless you're one of the users, who have to look for each letter on the keyboard, you have in less than one second, the window for the settings in his face. In Windows 8, I have to take and choose the mouse in the hand after typing "MOUSE" that I look for settings, because by default programs are selected as the search objects. It's annoying and I would put together programs and settings if I could.

The Start menu has so functional (almost) no plans to change. But the Modern UI goes even further. There is an app store, in itself is not bad, but unfortunately there is a huge drawback. From apps there can be only one instance of the time and this is always in full screen, so no two apps side by side (Ok, you can pin an app to the side, but not a true multitasking). On a 10 "tablet that may well be in order, as well as no longer fits so up, but at a desk that's total nonsense. But does not matter, because I must use any apps, for the replacement of Musikapp there are still Windows Media Player and place of Fotoapp you can still use the Windows Photo Viewer. Of course all Third Party programs work well. Apps are therefore additional and optional.

But unfortunately this Appprinzip goes further and specifically in terms of recruitment. There's the PC Settings app, under which, for example, are updates. If my Windows 7 update appears, then I got a small window that I pushed into a corner by the second monitor, so I had to progress at a glance. And Windows 8 will now for a display that only the content "updates are installed ..." has got a whole screen.
I have my 17 "notebook display and a 23" monitor next to it, which I can fully paste with windows at will, and now come the stupid apps and take me half of my work surface away. Imagine times before, you would have only one display available and must add on the Einstellungsapp a user or make any adjustments that are simultaneously reads from the browser does not work because the settings cover the whole screen.
But do not worry, all the settings there is still in the old windows version, as known from the Windows 7 Control Panel. But the update window does not appear, for example, when I search the Start menu to "update". And what is there not found there are not quasi for me because I run all about the search. The last time that I have (partially still to unfold) over hand me through the terrible hierarchical menu from the Start menu or Control Panel by was, in Windows XP, because it lacks the search and that is every time an ordeal. For a while with Vista or XP and later worked is inoperable, but that's another matter.
Fact is, there are the familiar control panel with all the settings. Only the setting for managing stored WiFi networks I miss since you need then again a third party tool that you have for so saved at ISOs and multimonitor.

One last thing. How to turn off the computer? Where is the button to shut down? Ins Start menu the way you can directly enter commands. So "shutdown / s" and Enter is definitely a possibility. But of course there is also a custom button, which is but hidden behind the "Charm Bar".
The thing about the shutdown and how to close apps, were things that I had to look for commands on the Internet, everything else is self-explanatory for Windows users.

Conclusion:
My notebook runs great, Apps must not use it and once you have made your settings, then disturbs not a new design. We then have a Windows 7 with a few improvements.
Is it worth an upgrade if you have Windows 7 running satisfactorily? Nope!
