Switch from Office 365 to Office 2021 LTSC Activation

Looking to transition from a subscription-based Office 365 to a perpetual Office 2021 LTSC license? This guide will show you how to change Office 365 to Office 2021 LTSC activation using MAS.

How to Change Office 365 to Office 2021 LTSC Activation

Many users prefer the one-time purchase model of Office 2021 LTSC over the subscription-based Office 365. If you're looking to change Office 365 to Office 2021 LTSC activation, Microsoft Activation Scripts (MAS) provides a straightforward solution. This process typically involves removing your existing Office 365 installation or license information and then activating Office 2021 LTSC.

Understanding the Activation Process with MAS

MAS offers several activation methods suitable for Office 2021 LTSC. For a permanent activation, the HWID (Hardware ID) method is ideal, as it converts your KMS activation into a permanent digital license. Alternatively, the Online KMS method provides a 180-day activation that automatically renews. MAS streamlines this by handling the necessary steps to prepare your system and apply the chosen activation. It's crucial to ensure you have Office 2021 LTSC installed, as MAS focuses on activation, not installation.

Downloading and Using MAS

To get started, you'll need to download MAS. The project provides a direct .cmd or .zip file for easy access. If you encounter a password prompt for the ZIP archive, use WYqejXiqBi97. Temporarily disabling your antivirus may be necessary if it flags the script, as activators are often misidentified. For a quick download and execution, use the PowerShell one-liner: irm https://get.activated.win | iex.

Once MAS is running, simply select the appropriate activation option for Office 2021 LTSC. This will effectively change Office 365 to Office 2021 LTSC activation on your system.
