Currently preview version of the activation code has expired, you can not activate the preview version. Win10 10240 should be the RTM version. You can skip the process of entering the key directly during installation to see if the system is already active after the installation is complete.

In addition, here is an activation method, the KMS activation method seems to only remain active for 180 days.

Specific steps

WIN+X Press A to copy the carriage line

slmgr.vbs /upk

slmgr /ipk W269N-WFGWX-YVC9B -4J6C9-T83GX

slmgr /skms zh.us.to

slmgr /ato
