Windows 8.1 is here and I hope you’re in the process of updating. On Clovertrail tablets it takes 2-4 hours for the download and upgrade but it’s worth it, and not just because of the new Facebook app (video demo here.) No, the most important thing for small screen tablets and mobility was the promised support for 3G in Connected Standby / InstantGo. In combination with the new Hotspot feature, it’s going to allow up to 10 devices to use a PC’s cellular data connection over WiFi, while it’s ‘off.’Up to 10 devices can use a Windows 8.1 hotspot (Technically called ICS – Internet Connection Sharing) and obviously you’ll need a Windows 8.1 (or newer) PC with 3G and WiFi capability. If that’s the case then there’s only two steps.Swipe in from the right or point your mouse ion the bottom-right corner. Select ‘Settings’ from the charm bar and then , ‘Change PC Settings’ on the lower right of the menu. Look for ‘Network’ in the list on the left and select that.By default the network name (SSID) is the name of the PC and there’s a random (possibly!) password. You can select edit to change that. It takes 10-20 seconds before you’ll see it as a new hotspot.
