Microsoft Windows 8.1 Pro 32/64 Bits Full Retail Version for
Windows online activation
Windows 8's big trick was bringing Microsoft into the tablet era,
with a more touch-friendly interface.
That change involved what Microsoft then called the "Metro"
interface and a new series of touch-ready apps for photos, video,
mail, and music. Microsoft also included a built-in store for users
to find and download new software.
Microsoft didn't go all the way toward a touch-ready future,
however. The company included a legacy "desktop" mode that could
run traditional Windows apps with the usual look and feel similar
to that of Windows 7.
Behind the scenes, Windows 8 also brought Windows into new
territory, supporting chips made by ARM Holdings -- the low-power
chips that helped fuel the rise and prevalence of smartphones and
tablets. Despite that, most consumers, developers, and later
hardware manufacturers opted to go with the version of Windows
running on x86 processors, which was backwards compatible with
Windows 8.1 represents a slight departure for Microsoft, with a
smaller upgrade that comes free of charge to existing Windows 8
The update is a collection of user interface tweaks, along with a
handful of behind-the-scenes changes. Key among them is the option
to boot straight to the desktop, as well as the return of the Start
button to launch apps. On the back end, Microsoft's added deeper
integration with its SkyDrive cloud service, along with Miracast
for wireless streaming over Wi-Fi to other Miracast-enabled
Other additions include an amped-up search tool that can dig
through files stored locally as well as on SkyDrive, support for 3D
printing, a new Xbox Music app, and better support for users with
Activate Windows 7 or Windows 8.1
Activation helps verify that Windows hasn’t been used on more PCs
than the Microsoft Software License Terms allow.
To activate Windows 7 or Windows 8.1, you’ll need a product key for
the version of Windows that’s on your PC. A product key is a
25-character code that looks like this:
PRODUCT KEY: XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
How to find your product key depends on how you got your copy of
Windows 7 or Windows 8.1:
If you bought Windows from an authorized retailer, the product key
will be on a label inside the box it came in.
If you bought a new PC running Windows, the product key will be
preinstalled on your PC, included with the packaging the PC came
in, or included on the Certificate of Authenticity (COA) attached
to the PC.
If you bought a digital copy of Windows from a Microsoft website,
the product key will be in the confirmation email you received
after buying it.
