  Weird situation: Office 2021 was fine for months, then an update happened and now it's asking for activation again. I remember someone mentioning activator KMS for Microsoft, but I didn't write it down. Anyone know a reliable KMS auto activator that works with the current Office builds?

  Right after a routine Office 2021 update, I noticed the top bar suddenly showed "Product Not Activated," and editing features started locking up. I hadn't changed anything in the system, so it felt like the update itself broke the validation. I didn't want to go through the hassle of calling support or digging for an old key, so I ran kms activator as a quick fix. It handled the reactivation silently, didn't trigger any warnings, and everything went back to normal instantly. That same version has stayed stable through two more updates, and I haven't had to repeat the process once.
