Activation error

0x803FA067

No valid digital license or product key for this hardware

Windows cannot match the current hardware to any digital license on record and no valid product key is present. The classic trigger is a hardware change (especially a motherboard) or a clean install of a different edition than the one the device's license covers.

Symptoms

"We can't activate Windows on this device because you don't have a valid digital license or product key. Error code: 0x803FA067"
The troubleshooter cannot find a license to reactivate
The device activated before the hardware change

Causes

A motherboard or other significant hardware change dissociated the digital license
The installed edition (for example Pro) does not match the license (for example Home)
The digital license was linked to a different Microsoft account than the one signed in

How to fix it

Sign in with the original Microsoft account

Sign in with the same Microsoft account used when Windows was first activated. Only that account's troubleshooter can see and reattach the digital license.

Use the hardware-change troubleshooter path

Settings > System > Activation > Troubleshoot, then "I changed hardware on this device recently". Select the current device from the list and activate.

Verify the installed edition matches

Run winver and confirm the edition. A Home license cannot activate a Pro install — reinstall the matching edition or supply a key for the installed edition.

Clear network-stack blockers

In an elevated prompt run netsh winhttp reset proxy and netsh winsock reset, then restart. Corrupted proxy/Winsock state can prevent the activation endpoints from being reached.
