You either need to use a third party tool, eg Partition Magic, or use wincd
to delete partitions then create new partitions of the size required.
Having a seperate partition for Programmes doesnt really add much, other
than showing what Programmes are installed, as if you have to wipe your Win
partition you will still have to reinstall all your programmes.
15gb should be more than adequate for a win partition.
