KMS activation for Office 2021

Office 2021 (including the LTSC editions) activates through KMS exactly like Office 2019. The Volume Licence build installs a Generic Volume Licence Key via the ospp.vbs script and activates against a Key Management Service host. On a single PC, KMSPico provides that host locally and handles the whole sequence in one run.

What you get

The full Office 2021 suite activated — no "Product Notice" bar, no editing restrictions — with activation renewing automatically every 180 days. Note that this applies to Volume editions; a personal Microsoft 365 subscription is account-based and isn't activated through KMS.

Manual activation

Run the cscript ospp.vbs commands shown above from an elevated Command Prompt to install the key and activate. For the dedicated activator page see Office 2021 activator, or the broader Microsoft Office activator.

KMS activations renew automatically every 180 days. As long as your machine can reach a KMS server, activation never visibly expires.

KMS activation works with Volume License editions of Office. Retail/Microsoft 365 subscriptions use a different activation method.

Yes. KMSPico performs local KMS activation — no Microsoft servers or internet required during the process.
