I also think your approach isn't feasible. The following batch/vbscript only gave me a small percentage of useful renames ( @Vinayak I'd apppend a -Whatif to the copy can't comment)
The batch outputs rename commands you may redirect to a file like ´DoRenames.cmd`and after revision execute.
::ListLnkProps.cmd:::::::::::::::::::::::::::::::::::::::::::::::::::
@echo off&setlocal enabledelayedexpansion
:: create .\ListLnkProps.vbs
for /f "tokens=1 delims=:" %%A in (
'findstr /I /N "##ListLnkProps" ^<"%~f0"') do set /A ln#=%%A - 1
more +%ln#% "%~f0" >"%~dpn0.vbs"
:: List.lnk file properties in curent folder and subfolders
for /f "delims=" %%A in (
'dir /A-D /b /s *.lnk'
) do cscript //nologo "%~dpn0.vbs" "%%A"
goto :eof
' ##ListLnkProps.vbs
set WshShell = WScript.CreateObject("WScript.Shell")
File = WScript.Arguments.Unnamed(0)
set Lnk = WshShell.CreateShortcut(File)
NewName = Lnk.Description & ".lnk"
If Len(Lnk.Description) > 8 Then
wscript.Echo "Ren " & chr(34) & File & chr(34) & " " & _
chr(34) & NewName & chr(34)
End If
set Lnk = Nothing
