3. Things to keep in mind
Unexpected PC crashes could damage or even delete your files, so you
should back up everything. Some printers and other hardware might not
work, and some software might not install or work correctly, including
antivirus or security programs. You might also have trouble connecting to
home or corporate networks.
Some installed apps might not yet work as expected or might not be available
in your country or region. For example, Cortana is currently only available in
English (United States), English (United Kingdom), Chinese (Simplified),
German (Germany), French (France), Italian, and Spanish (Spain). To be able
to use Cortana, the country or region for your system must be set to one of the
