The System Recovery feature in Windows 8 and 10 is a great feature that enables you to fix your computer if it ever gets stuck in a state in which it will not boot properly. A number of tools are included, such as Automatic Repair, System Restore, Refresh your PC, System Image Recovery, and Memory Diagnostics, along with a way for you to access the command prompt.
To get started, you will need a USB flash drive that is 256 MB or larger and plug it in.
Open the Start screen, type in recoverydrive.exe, and then hit Enter.
On the Recovery Drive window, click Next.
