My friend upgraded her HP Probook 4525s from Windows 7 to Windows 10 via the streamed upgrade she was offered. She can't remember exactly what she did, but we have now a Windows 10 login screen for which the account is called &quot;Recovery&quot; and for which we need a password which we don't know. &nbsp;Her own account password doesn't work. &nbsp;I've tried enabling the built-in administrator a/c as you could with Windows 8 using a Windows 8 CD, but this doesn't bring up the command line at the login screen as it would with Windows 8. &nbsp;Has anyone anyone seen this behaviour before and have any idea how to fix?<br />

My friend upgraded her HP Probook 4525s from Windows 7 to Windows 10 via the streamed upgrade she was offered. She can't remember exactly what she did, but we have now a Windows 10 login screen for which the account is called "Recovery" and for which we need a password which we don't know.  Her own account password doesn't work.  I've tried enabling the built-in administrator a/c as you could with Windows 8 using a Windows 8 CD, but this doesn't bring up the command line at the login screen as it would with Windows 8.

Windows 10 is a personal computer operating system featuring the "universal application architecture" (UAP); apps can be designed to run across multiple devices with nearly identical code, including PCs, tablets, smartphones, embedded systems, Xbox One, Surface Hub and HoloLens. Windows 10 also includes a virtual desktop system, a window and desktop management feature called Task View, the Microsoft Edge web browser, support for fingerprint and face recognition login, voice-based search (Cortana), new security features for enterprise environments, and DirectX 12 and WDDM 2.0 to improve the operating system's graphics capabilities for games.

Windows 8 is a personal computer operating system developed by Microsoft as part of the Windows NT family of operating systems, with an emphasis on improving its user experience on tablets.

Additional security features were introduced, such as built-in antivirus software, integration with Microsoft SmartScreen phishing filtering service and support for UEFI Secure Boot on supported devices with UEFI firmware.
