How to Reset Your Surface
Resetting is a last-resort option that wipes your Surface completely clean, removing everything. When it wakes back up, it behaves like it was just removed from its shiny new box. It’s a drastic measure, but it’s one that always works when your Surface seems beyond repair.
The resetting process
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.
When your Surface returns to life, it then behaves just as it did when you first turned it on, and you need to choose a language and begin installing updates.
Servicing your Surface through Microsoft
If your Surface includes problems you can’t fix alone, drop by Microsoft’s website for further help.
After you enter your Microsoft account, the website walks you through registering your Surface, reporting problems, checking the status of service orders, checking your warranty status, replacing accessories, and, if desired, buying a service plan.
To find your Surface’s serial number, flip open its kickstand; it’s printed below the word Surface. The serial number for your Touch or Type keyboards is printed on the right side of the keyboard’s spine. (You need to detach the keyboard from your Surface to see it.)
