Compared to the old Windows 8.1 Metro Calendar app, the new Windows 10 Calendar app (Figure 3) looks like a usable Calendar, right out of the box. As with Windows 10 Mail, you can click on the hamburger icon and shrink the first column down to a bunch of icons.
Click on the Day column and you can choose from two-day up to six-day views.
In my brief tests, the new Calendar app appears to work correctly with Google Calendar, but I had long delays in syncing changes made to Google Calendar entries outside of Windows 10. (Note: In spite of what you may have read, Windows 8.1's Mail supports Gmail accounts. The big change here is Google Calendar support in the Calendar app.)
While working with a browser on the Google Calendar site from inside build 10051, I couldn't get either Project Spartan or IE11 to properly set new events. That isn't a Calendar app problem, but a browser problem — probably more beta blues.
There's a new Metro, uh Universal, er Windows app called Microsoft Family. Not sure what it's supposed to do — running it just brings up a white window — but it's undoubtedly tied into the old Windows Family Safety account-limiting shtick.
Spartan now has a new entry in the ellipses (. . .) menu called Open with Internet Explorer. Choose it and the current page gets opened by IE11, with a pane left behind requesting your feedback.
WZor also leaked a copy of the official Windows 10 Tech Preview Release Notes for build 10051.
If you really want to see what the new Mail and Calendar apps will look like, build 10051 may warrant a peek. For most Windows 10 wannabe users, it isn't worth the effort.
In other Windows 10-related news...
On Friday, Microsoft Chief Privacy Office Brendon Lynch posted a statement promising that Do Not Track would not be enabled by default in Internet Explorer (or, presumably, Spartan). Theoretically, Do Not Track is supposed to tell websites that they shouldn't track you. In practice, very few sites bother with it. Microsoft is just now coming into compliance with a spec set in stone years ago — one that doesn't mean much anyway. Gregg Keizer has a good overview. Stick a fork in it.
Microsoft posted an acknowledgment of the bug in the build 10041 and 10049 installers, which may fail if there isn't enough disk space or may take hours to install. The solution on offer isn't much help: Free up 2.5GB of disk space and suck it up. Apparently in some cases, for unknown reasons, the installer downloads all available language packs. I personally hit a variant of the problem when the build 10049 installer placed two new folders on my desktop: Korean Messenger Center and Korean Media Player Center. No, I don't have the Korean language pack installed. Beta blues.
