While the demise of Windows XP may be sad news for some people, there's happy news coming out of Redmond today as the much awaited Windows 8.1 update is finally rolling out and available to current Windows 8.1 users for free. Coming in the Mother of All Patch Tuesdays, the new update offers refinements to the current Windows 8.1 experience highlighted here. While Microsoft says it will take a few weeks to reach all users, I just went into Windows Update on my Surface Pro and the update was available along with a half-dozen others. Grab a cold beverage, some popcorn and get with the latest version of Windows now.
