We all know that last night Microsoft made available Windows 8 Release Preview for everyone and everyone (including me) all over the world are too much excited for it. After installing Windows 8 Release Preview first activate your Windows 8 and then check for updates if any.
When I checked the updates, I found there are 3 new Windows 8 Release Preview updates for it which included Update for Windows 8 Release Preview: KB2716368 and KB2717246 & Definition Update for Windows Defender – KB2267602.
Kindly update your Windows 8 RP with their new updates so as to make your system up to date.
Note: It’s necessary to keep your System updated not only for security reasons but also for compatibility as new updates for your devices and drivers updates also released by their vendors.
