Enable Revit 2010 / Revit 2011 to use Revit 2009 interface.

Here we go. Update to Autodesk Revit Architecture 2010 or Autodesk Revit MEP 2010 or Autodesk Revit Structure 2010 (or a newer version). Nice. You open the new version; you dislike the new user interface (probably you have already seen something similar in Autocad 2009 and newer versions, and yes, you disliked it too). You don't need to look far to realize that you want switch back to the classic user interface.
You can not.
Maybe here, there… you can not!
But you are a professional of Autocad, you know there is always a way (see drawing 1). Probably you are now working with Autocad 2010 and the classic interface. For sure you will find it for Revit.
You look for again, and again… “User interface” “Workspace switching” …sorry… no way!!.

Ok, Autodesk. "How to switch back to the old Revit interface?"... One hour later you are here…

“Switching to pre-2010, Classic user interface
Published date: 2010-Apr-12 ID: TS1106335
Applies to:
Autodesk revit Architecture 2010, Autodesk revit Architecture 2011
Autodesk Revit MEP 2010, Autodesk Revit MEP 2011
Autodesk Revit tructure 2010, Autodesk Revit tructure 2011
Issue
You want to know if you can switch your user interface back to the pre-2010 user interface.
Solution
There is no supported way to switch back to the previous user interface.
It is possible to enable the Revit 2009 user interface in a Revit 2010 or later version product, but no support will be provided for problems that occur in that environment that are not reproduced in the standard ribbon user interface...”

Surprise?
You are a professional designer with so many years of experience. You are used to update. You have to. Almost every year you get a new version of the program that you are already familiar with. Years ago you used to complain to your partner, your friends, the baker, the neighbours, your colleagues and of course your boss... No one understood anything about it. Now, you know that there is nothing to be done. Even that you can happily update or angrily update. But you must update. And of course, do it the more happily as possible. :o)
Usually there are not many surprises. But sometimes when you open the new program you get a new user interface, and this can be very funny.
Or hilarious, wondering if this is still the same program.
And after checking the new interface and realizing that the new user interface is bad, very bad (like this one from Revit 2010), you want to switch back to the classic nice user interface that you were used to.
And that is the question. To do or not to do?. If I enable the Revit 2009 user interface not support is provided for problems outside the ¨standard ribbon user interface¨. :o(

After careful consideration I have decided not to enable Revit 2009 interface. Why? if I don’t like the new one:
First because the probabilities that version Revit 2012 and newer doesn’t support 2009 interface are very high. I prefer the ¨classic one¨ but this time Autodesk got me.
Second because when I am updating to a new version the probability need the support is high.
And finally because I have seem, casually, there are increasingly more programs that are using this ugly slowly kind of ribbon user interface.

Because I am going to do it, today is the best day to start. Of course I will do it the more happy as possible. :o)
...internet search …and voilà!!!… look at this!!… nice people around the world:
