How to Reset Your Surface
This last-resort option wipes your Surface completely clean, removing everything. When it wakes back up, your Surface behaves like it was just removed from its shiny new box. Although it’s a drastic measure, this last-ditch effort can often salvage a Surface that seems beyond repair.
Resetting your Surface is also a good way to restore your Surface to factory conditions before giving it away, either to friends or charity.
Resetting your Surface deletes all of your personal files, apps, desktop programs, and settings.
To reset your Surface to factory conditions, follow these steps:
Swipe in from the right edge of the screen, tap Settings, and then tap Change PC settings.
Tap the General category.
In the section called Remove Everything and Reinstall Windows, tap Get Started, tap Next, and follow the instructions.
If you’re giving away your Surface, choose the Fully Clean My Drive option. That option takes much longer, but it scrubs your drive clean of any identifying information.
When your Surface returns to life, it behaves just as it did when you first turned it on, and you need to choose a language, set up your accounts and begin installing updates.
