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 🙂
