If you want to access the Windows App Store or use Windows apps, your monitor's resolution needs to be at least 1024x768,windows 10 Technology Preview currently has English, Simplified Chinese and Brazilian Portuguese in several languages.

Windows 10 is a very early version, so it is not appropriate to overwrite your existing operating system-especially considering that it will make Windows Media Player unable to play DVDs and remove Windows Media from the upgraded Windows 8.1 Professional Edition Center.

Installing in a virtual machine is the easiest choice. With the help of Oracle's free virtual machine tools Grad VirtualBox, you can experience Windows 10. The configuration used to install the system in the virtual machine is almost identical to that of Windows 8, and users should not encounter any problems during installation.

If the installation fails, try adjusting the following configurations, after completing the initial setup of Windows 10, turn on the Virtual machine tool Settings > System menu. Under the "Motherboard" tab, make sure that the "open EFI (special system only)" box is checked. The "Open Pae/nx" under the "Processor" tab is the same.

Running the operating system in a virtual machine can sacrifice part of the performance, especially if you don't have the extra CPU core or memory space to perform this task. If you want to experience Windows 10 natively, you can create a new partition on your hard disk and install the system in the new partition.
