Manually activate win11, the keys for win10 and win11 are universal, which can activate the serial number of win10 and win11. The kms activation tool was used before, but it was only valid for half a year. The antivirus tool and firewall had to be turned off for each activation. Even if the kms permanent activation tool was later replaced, there was still a fear of virus bundling. Manually activate win10, which is safe and reliable, and win11 is permanently activated!
