Common checks
Before asking for help
Most activation issues come from edition mismatch, skipped phone activation steps, or expired private order links.
Check the Windows edition
A Pro key will not activate Home, and an Office key will not activate Windows. Match the product name on your order page.
Do not close the phone activation window
The Confirmation ID is tied to the Installation ID on that screen. If you restart the flow, send the new Installation ID.
Change the temporary password
After first sign-in, Microsoft may ask you to update the password. Save the new password because Delta cannot see it.
Use the private order link
Your delivery link contains the key, account details, and activation tools. Keep it private and do not share screenshots with the full key.
