"Microsoft" handles spaces in paths just fine.

I don't know why tar isn't in this case but you can work around the problem
by mounting the directory as something else:

mount -f -x -b c:/"Documents and Settings"/Liedtke/"My Documents" /foo

And then refer to "/foo/Tasks/Backup/rename.sh".

I haven't tested the above and may have a typo but hopefully it is obvious
nonetheless.  If not, then possibly "man mount" would help.
