How to restore, refresh, or reset your PC
If you're having problems with your PC, you can try to restore, refresh, or reset it. Restoring your PC is a way to undo recent system changes you've made. Refreshing your PC reinstalls Windows and keeps your personal files, settings, and the apps that came with your PC and apps that you installed from Windows Store. Resetting your PC reinstalls Windows but deletes your files, settings, and apps—except for the apps that came with your PC.
Restore your PC to an earlier point in time
If you think an app or driver that you recently installed caused problems with your PC, you can restore it back to an earlier point in time, called a restore point. System Restore doesn’t change your personal files, but it might remove recently installed apps and drivers.
To restore your PC using System Restore
Swipe in from the right edge of the screen, and then tap Search.
(If you're using a mouse, point to the upper-right corner of the screen, move the mouse pointer down, and then click Search.) Enter Recovery in the search box, tap or click Settings, and then tap or click Recovery.
Tap or click Open System Restore, and follow the prompts.
Refresh your PC without affecting your files
If your PC isn't performing as well as it once did, and you don't know why, you can refresh your PC without deleting any of your personal files or changing your settings.
To refresh your PC
Swipe in from the right edge of the screen, tap Settings, and then tap Change PC settings.

You'll be prompted to choose whether you want to erase data quickly or thoroughly. If you choose to erase data quickly, some data might be recoverable using special software. If you choose to erase data thoroughly, this will take longer but it makes recovering data far less likely.
