You can use FOR and %ComSpec%, but that will remove from 000 to x.

You can count with FOR too, if you know the exact number of files:

<remove cmd='%ComSpec% /c FOR /L %C in (9,-1,0) do "%PROGRAMFILES%\Aspell\unins00%C.exe"' />

If the number exceeds 9 you need to add another line as follows:

<remove cmd='%ComSpec% /c FOR /L %C in (99,-1,10) do "%PROGRAMFILES%\Aspell\unins0%C.exe"' />

You need at least Windows XP to make this work, I think.

The other solution is creating a file containing all the unins... file names, sorting it in reverse order and run each of the files.

For batch scripting, you can find many hints at http://www.robvanderwoude.com/.

You could create a JS script or batch file to do this too, so you could add more error checking there.
