Upgrade your Windows 10 setup from Home to Professional version.
Upgrade your Windows 10 setup from Home to Professional version.
Upgrading directly to Pro will remove your current apps, yet your information remains safe. However, this process can be complicated, so it's wise to copy your data to another external or backup drive. REMEMBER: Always disconnect your secondary HDD before starting the Windows installation to avoid accidental formatting.
The issue seems to stem from the key not being recognized by Windows 10 Home. It appears the key might be invalid or corrupted, which could explain why the upgrade process failed without any loss of files or programs.
