I submitted Windows 8.1 update (Release 3) to the App store on Friday afternoon and received notification at 11PM PST on Sunday that it is published. Windows 8.1 version of the executable is 18.104.22.168 to differentiate it from Windows 8 version 22.214.171.124. Variable grid control behavior was the only thing that really had to be updated. I didn’t have any time to add new features or code around deprecated in Windows 8.1 runtime features.
Windows 8.1 feels like a really solid product: noticeably faster, takes up less space on the hard drive, desktop experience is back as the primary environment with modern UI now blending in. I set the same background for both the Start screen and the desktop. Now it feels like there is no split personality effect any more (well, at least the human perception part is taken care of). I really like new support for multiple resizable windows in the modern UI part of the “split personality”. VS2013 is another excellent product that came out. Just try Alt+F12 for code peek and you will be hooked. No more losing where you were when jumping around solution. These things make huge difference. .Net4.5.1 cold assembly startup is noticeably faster too. I updated my USB drive with “Windows 8.1 To Go”. App store is no longer blocked (that was really annoying in “Windows 8 To Go”). Overall this OS upgrade is a huge step forward. Perfect timing too since XP is coming to the end of its life support.
