Windows 8.1 will come with some nice features both for corporate and personal use. Only some features will highlighted here and mostly those that will be on personal use.

Tethering
At last windows brings tethering to the PC without the need for third party applications. You can now turn your PC to a hotspot after updating to Windows 8.1 and have other devices tap into your internet connection if you so wish.

Improved bio-metrics
Like it or not bio-metrics as a security feature has come and to stay. Though this feature is not new and has been on previous versions of windows some thoughtful improvements have been made here. Windows 8.1 will also be optimized for fingerprint based bio-metrics and will include a common fingerprint enrollment experience that will work with a variety of readers (touch, swipe). Modern readers are touch based rather than swipe and include liveliness detection that prevents spoofing (e.g.: silicon emulated fingerprints). Access to Windows Store Apps, functions within them, and certificate release can be gated based on verification of a user’s bio-metric identity.

Improved internet explorer
Microsoft says the improvements in Internet Explorer 11 will make it load faster, with a side-by-side browsing of sides (what I call multitask browsing).

Desktop and start screen
For those who prefer the mouse and keyboard experience, you've have not been left out as improvements have been made to accommodate you.
