My best advice would be don't do it. But if you must, dig out a copy of Partition Magic which has a utility called Drive Mapper. This will allow you to change all the references from the old drive to the new one after you have moved them. Better still, older versions came with a thing called MagicMover which did it all for you. Usual caveats apply.
and reinstall it to the new partition. Installers put keys in your Windows registry, and unravelling these entries can be incredibly complex. The otential for error is huge, and it's just not worth the effort. Reinstallation isn't really that onerous, and you'll be glad you did it that way.
Several programmes (Quaterdeck's [now Norton's] Cleansweep) and Partition Magic's Drive Mapper, among others promised to do this, but as Forum Editor has indicated a reinstall is the best solution.
Take the opportunity to do a major rearrangement, but as ever, take a COMPLETE backup, preferably a Norton Ghost image or a Drive Image. Then if, or should I say, when all hell lets loose you can get back to where you started.
