interesting, even in latest insider builds, didn't have problem with ZeroCid going to test latest uup dump insider build and check --> Still work .. no bug ?
Tech speak Uup dump offer 25h2 if I don't mistake Build number and ubr number should match build number that should fail After installing the system ubr value is lower than what published But static cid and zerocid both work And I test few build like that Maybe this bug not persist, maybe for specific beta build's But beta build's are beta, so, use kms4k in case of beta
