Windows 8.1 to Windows 10 upgrade stuck at 2% [SOLVED]
Problem: Windows 8.1 to Windows 10 upgrade stuck at 2% 🙁 Solution: Cancel installation (CTRL+ALT+DEL, taskmanger, kill install task) Open Windows Command Prompt (as administrator) and run: sfc /scannow A error will likely be detected and Windows will attempt to correct it. After the error is fixed, re-run the Windows 10 update 🙂
