File Extension change
This is suppose to be straightforward but it's not, I need to change the file extension using a batch job on files with .txt extension to .bak, what the simplest way.

Yes,
And that's my issue, I need to retain the name(s) of the file(s) but only change their extension.

I would use vbscript for this. Save the code below to a .vbs and change "C:\MyFolder\" to the folder you want to work from.
Option Explicit
Dim fso, strFldr, colFiles, objFile
strFldr = "C:\MyFolder\"
Set fso = CreateObject("Scripting.FileSystemObject")
Set colFiles = fso.GetFolder(strFldr).Files
For Each objFile In colFiles
If Eval ("txt" = fso.GetExtensionName(objFile)) Then
fso.MoveFile objFile.path, Left(objFile.path,Len(objFile.path) - 3) & "bak"
End If
Next
NO, "Ren" expects a literal in the second half of the command, "*. etc." works well with Delete, Copy, etc., not with "Ren"
Open Notepad and paste the code in then save it with a .vbs extension. To call it just double click it.
You can call it from the command line too

cscript.exe C:\Path\To\Script.vbs
The command I suggested will certainly work fine, here's an example.
C:\Temp\ee>dir
Volume in drive C is Windows 7
Volume Serial Number is 0000-0000
Directory of C:\Temp\ee
12/27/2012 01:17 PM <DIR> .
12/27/2012 01:17 PM <DIR> ..
12/27/2012 01:17 PM 2 1.txt
12/27/2012 01:17 PM 2 2.txt
12/27/2012 01:17 PM 2 3.txt
3 File(s) 6 bytes
2 Dir(s) 4,508,450,816 bytes free
C:\Temp\ee>ren *.txt *.bak
C:\Temp\ee>dir
Volume in drive C is Windows 7
Volume Serial Number is 0000-0000
Directory of C:\Temp\ee
12/27/2012 01:17 PM <DIR> .
12/27/2012 01:17 PM <DIR> ..
12/27/2012 01:17 PM 2 1.bak
12/27/2012 01:17 PM 2 2.bak
12/27/2012 01:17 PM 2 3.bak
3 File(s) 6 bytes
2 Dir(s) 4,508,454,912 bytes free
Thanks, it worked,
Can I call a .vbs from a batch file (I'm thinking I should be able to), what do you think?
Thx
