I normally wait for updates for a week or so and scan all the Forums for issues before installing them.
Other than the casual user i'd suggest this for most knowledgable users.
That being said today i grabbed the latest updates ( 4 ) from the last Patch Tuesday...
These require a re-boot and the system will appear to hang in the process...NOTE...be patient and let it finish.
On the Benchtest machine the wait was over 12 minutes...which may alarm some casual users.
To test i repeated the process on the same machine but a different build of Vista...2nd build was close to that...approx. 9 1/2 minutes.
Just as a heads up...always let the update process finish...no matter if it appears to hang or not.
These are the Updates:
KB915597
KB890830
KB969947
KB973565
If you run into this as i said let it complete...and pass the word to any Vista users you may know.
