Vista SP1 - Update 3 of 3 boot loop

Latest suggestions (as of 25 June 2012):
 - del C:\Windows\WinSxS\cleanup.xml
 - del C:\Windows\WinSxS\pending.xml
States that it applies to Win7 also.


Lot's of users are reporting successful SP1 installations - so for most people the XP SP2 debacle is now ancient history. But a few people are having issues - particularly with reboot loops at step 3. It'll be interesting to see what's causing it.

I haven't seen any drastic performance improvements with it, and it'll take a while to see any reliability or security improvements - but all in all it seems to be a worthwhile update.

The fix of renaming pending.xml to something else seems to be the most popular.
Some will boot into Safe Mode to remove some offending updates
Others will use System Restore with limited success (recent restore points may not work, may have to go back several days).

This article says essentially the same thing (but gives a priority to the above suggestions):  Link no longer works
