TweakUI & Vista's restore points (Feedback, please)

As we all know, if you dual-boot XP and Vista,
XP's volsnap.sys will delete Vista's restore points
and shadow copies. We know the two fixes- hide
Vista's partition from XP or if you have Ultimate,
BitLocker will protect Vista.

I have seen some users suggest using TweakUI
to hide Vista's partition. An MVP has this posted
on his website as an option. I have seen this posted
in on several websites. However, I have seen quite
a few folks say that TweakUI doesn't actually work
properly in hiding Vista's partition and their restore points
are deleted. Has anyone verified if TweakUI actually does
protect Vista's restore points by hiding Vista's partition?

I would appreciate feedback on this. Those that have used
TweakUI, booted to XP and then back to Vista, and still have
their restore points. Successful and unsuccessful.

Before I recommend this to anyone, I really would like to
hear from those that have tried it. Unfortunately, I haven't
tried it, yet. I'm using BitLocker to protect Vista on this machine.

Thanks guys.
