Activation error 0x8007000D on Windows Insider build 10.26200

I’m on Windows Insider build 10.26200 (Windows 11 Pro). When I try to activate the system, I get error 0x8007000D. The activation wizard (slui 4) does not open at all. Standard activation methods do not work with this Insider build.

I’m signed in with a Microsoft account. Please advise how to proceed or help with server-side activation.

    Hi Ruslan, 0x8007000D usually points to corrupted activation data or a damaged system component, and Insider builds can make that messier. I would run the Activation troubleshooter, confirm the installed edition matches your license, then run DISM and sfc /scannow. If slui will not open and the build is unstable, the practical fix may be rolling back or clean installing a stable build and activating there.
