The Windows 10 user experience is coming together.
The signature feature of Windows 10 is, of course, the Start menu, which blends a Windows 7-style Programs list on the left with a larger palette of Windows 8-like tiles on the right. The screenshot above shows the default Start menu in a Parallels virtual machine running on OS X Yosemite. (That configuration works very well, by the way.) In this build, the File Explorer, Settings, and Power apps move from the top to near the bottom of that left column, with an All Apps link leading to an alphabetical list of programs and program groups. The menu is resizable as well, and search results (with or without Cortana) are more tightly integrated into the menu space.
Push Button Reset makes a clean install ridiculously easy.
For an 18-month-old Dell Venue 8 Pro tablet, I used the Reset option this morning to restore the original Windows 8.1 factory image from late 2013, which then required literally hundreds of updates, multiple restarts, and way too much babysitting for too many hours before the device was usable. Windows 10 can still use those Windows 8.x factory partitions on upgraded devices, but the new OS is capable of generating a clean install image from its own system files. I decided to try that option on a virtual machine that had been upgraded several times and was using nearly 40 GB of a 64 GB drive. The entire process took less than an hour, with one additional short wait near the end when I signed in with my Microsoft account.
The included apps are improving dramatically.
The MSN family of apps–Money, Weather, Sports, News, and so on–are good showcases for what the platform can do. They're much richer than their Windows 8 predecessors, with designs that scale very nicely from a small, phone-sized window to larger screens. I'm still in the process of wrapping up installations on a pair of small tablets, but so far what I have seen is very nice. I'll share more about the tablet experience in a follow-up post.
