This past weekend, I assisted one of my friends in upgrading Windows 7 installation to the recently released Windows 8.1 version. The upgrade was smooth, even though the operation doesn’t keep installed programs and one needs to install all programs all over again after completing the upgrade. After upgrading to Windows 8.1, we reinstalled all the desktop programs and also made sure that all drivers have been updated to the latest available version. While attempting to turn on Bluetooth, my friend noticed that Windows Mobility Center can’t be launched with the old Windows + X hotkey as pressing Windows + X keys reveals power user menu (also known as Win+X menu) in Windows 8 and Windows 8.1. For those who aren’t familiar with Windows Mobility Center, it’s a feature available on laptops and tablets to quickly change screen brightness, Bluetooth, Wi-Fi, sync, display, sound and battery settings. In Windows 7 and Vista, one could quickly launch Windows Mobility Center by simultaneously pressing Windows logo and X keys.
