Latest Vista64 updates (Jan 8/9) created problems

In case it helps anyone else:

My Vista64 Ultimate notebook (Asus G2S, Core Due 2.2GHz, 2GB RAM) was behaving perfectly until I installed today's recommended updates from M$ - the new installer, reliability update and also KB943302, plus a couple of lesser, older ones including a bluetooth driver (optional update).

The install process itself was dodgy - during the shutdown part of its restart, it stayed at the "Installing updates" for 20+ minutes and then moved to "Shutting down" for at least another 20-40 minutes before I finally lost patience and did a hard power off.

On restart, it 10-20 minutes at "Configuring updates" but did evenually return to a logon screen. But I found that mouse and touchpad actions were "freezing" for a split second every few seconds. Just in case, I did a bluetooth mouse remove/re-add, but that changed nothing.

A few minutes later it spontaneously went into shutdown, and has been at "shutting down" ever since. I'm being even more patient this time - at least an hour and counting. At this point, I have no idea whether I'll eventually get joy, or just end up having to system restore, or worse.

These are small updates, hardly SP1 RC or anything!

Be careful out there.
