First of all, thanks for this excellent tutorial! As of now, everything works fine.
Question 1 : Can I get the default Windows 10 status bar back (while keeping the Details pane at the bottom) ?
After installing OldNewExplorer and following your tutorial I got this : http://i.imgur.com/azY4jKS.png

Question 2 : Is there a way to get rid of the "Availability" section in the Details pane?

I see that some people have trouble getting the desired result so maybe I can be of some help.
My goal was to move the Details pane to the bottom by editing the original Windows 10 theme (Windows 10 x64, as of today - all updates installed, no patched files, no custom themes, etc. , ..., i.e. an untouched Windows 10).
I managed to do so by following the original tutorial : http://www.msfn.org/board/topic/175131-how-to-move-details-pane-to-bottom-without-memory-patching-win10/?do=findComment&comment=1115926
I didn't have to use the more complicated approach described here : http://www.msfn.org/board/topic/175131-how-to-move-details-pane-to-bottom-without-memory-patching-win10/?do=findComment&comment=1116650
Some guidelines :
Before doing any step of the tutorial, install OldNewExplorer
Follow the tutorial steps until you have two steps left (i.e. step 9 and 10 i.e. 9th and 10th bulletin point). After you saved a copy of the modified shellstyle.dll somewhere on your computer but before replacing the unmodified version, do the following:
make a backup copy of the unmodified version
take ownership of the original unmodified version (in my case : "C:\Windows\Resources\Themes\aero\Shell\NormalColor\shellstyle.dll") - the easiest way to do so is adding a "Take Ownership" option to the Win10 context menu - see here: http://www.tenforums.com/tutorials/3841-take-ownership-add-context-menu-windows-10-a.html
before you replace the unmodified version with the modified shellstyle.dll, change your theme to a High Contrast Theme : http://i.imgur.com/o5T5vAF.png
replace the unmodified shellstyle.dll with the modified shellstyle.dll
change your theme back to the one your try to modify (in my case: High Contrast Theme -> Aero Theme)
restart your computer and you are done!
