Several users have reported that their update download would pause somewhere around the 6% mark, and then it would resume without issues.

My desktop machine had some trouble downloading the update this time. It sat unexceptionally long at 6% downloading. I looked at the Perf mon and saw a fault there. TimeZone Sync Task stopped working.
