For all you happy users here in the US, We have an early Daylight Saving Time this year, thought I'd thow out some important Technical assistance to all you happy Microsoft Outlook users.
For starters, to patch windows to automatically update, download and install
KB931836. If you have Automatic updates turned on, this is likely already installed and you can check by going to Add/Remove programs under your controll panel, checking the "Show Updates" button at the top and looking for KB931836 down twoards the bottom of your list.
Now, the important part that most people seem not to know about. If you have the patch for windows installed, you will probably notice all of the apointments in your calendar and any times/dates in Outlook are off by an hour for the next three weeks! The way to fix this is by running an update provided by Microsoft.

This update will fix the appropriate time zone data in Outlook so your calendar apointments and associated dates/times are not all screwed up. For any IT folks out there, there is a program available from Microsoft to apply this to an entire exchange server, just go look on techet for tzmove.exe.
Hope that helps at least someone out there.
