Stop windows from updating
This will help you recover the lost, deleted, and inaccessible data from not just the PC but also the various external storage media connected to it. If none of those mentioned above methods works, it means there is some major issue with your system. Hence, backup your data before proceeding to Windows 10 re-installation.
Windows 10 may get bugs sometimes, but the frequent updates released by Microsoft bring stability to the operating system.(And it's one of the reasons you might not want to upgrade to Windows 10 just yet.)If you're running a professional version of Windows 10 (Professional, Enterprise or Education), you actually can disable automatic updates using the Group Policy editor.But if you -- like most people -- are using Windows 10 Home, you'll need to use workarounds to stave off Windows 10's aggressive automatic updates.Such issues with Windows updates may cause data loss due to a sudden system restart.Therefore, change the windows updates policy – as discussed in the post – to avoid automatic system shutdown.
