Defect #20028: Registry entry under HKLM\\software\\microsoft\\windows\\currentversion\\uninstall is not deleted in 64 bit environment

When uninstalling QGIS 2.8.2 Wien on a Windows 7 x64 OS, the entry in Add/Remove Programs is not deleted. This is because the associated registry entry "HKLM\\software\\microsoft\\windows\\currentversion\\uninstall\\QGIS Wien" is not deleted.
This is not a Problem because it is easy to do this manually or by a Batch file but i wanted you to know this little issue.
And while looking at this, you may also add the "DisplayVersion"-Registry-Value too. =)
Another Thing i noticed is that the Desktop-Shortcuts are named differently in x86 and x64 installer. I.E:
OSGeo4W (x86) and OSGeo4W Shell (x64)
MSYS Shell (x86) and MSYS (x64)

Issue still exist in 2.14.2 Essen.
Also the RegKey "HKLM\\Software\\QGIS ESSEN" is not deleted during uninstall on a 64 bit system.
Problem with this key is that if you uninstall the software and want to install the same Version again it stops with an error.
