Microsoft removed the option for local PC migration on Patch Day in October 2026 with update KB5127648. This change had already been announced in September 2026 via the optional update (Windows Preview) KB5124010. So, with Windows Backup, data now follows this path: old Windows computer > Windows Backup > Microsoft cloud storage (OneDrive) > new Windows computer.
As well as the additional cost of extra storage on OneDrive, another drawback is that your data leaves your local network and passes through Microsoft’s servers. Furthermore, you must have a Microsoft account to do this. Anyone wishing to use Windows 11 without a Microsoft account cannot use Windows Backup.
With the now-discontinued PC-to-PC migration, you could transfer data and account information from an old Windows computer to a new one via your local network. This process took place entirely over your local network; both Windows computers simply had to be on the same network.
