Today I decided to upgrade my Surface Pro running Windows 8.1 to the Windows 10 Technical Preview. I copied the ISO to a USB and inserted into the Surface. I kicked off Setup and first option was to Choose what to Keep. You have three choices here depending on what you want to keep. I chose the option to Keep Windows settings, personal files, and apps and moved on. after confirmation, the installation continues and about 20 mins later, Viola! Windows Technical Preview for Enterprise.
After the install I noticed that the new Start Menu was not present, probably because I choose to keep my settings and the old setting for the Start menu remained. You can enable it by right-clicking the taskbar and going into the properties page for the Taskbar and Start Menu. Under the Start Menu select “Use the Start menu instead of the Start screen”.
This shows you just how simple this upgrade really is. I was curious to see what was working and what wasn’t. To my surprise everything just worked, Office 365, Lync , and OneDrive. Good job Microsoft.
