At the beginning of this year, Microsoft quietly pulled the plug on the last way to activate Windows 10 or Windows 11 without an Internet connection. Up until that point, it was possible to activate Windows without the Internet using your telephone.
While Microsoft didn’t announce the feature's deprecation, the corresponding menu item in Windows remained available. Multiple users lodged complaints, citing that an attempt to call the activation hotline only redirected them to online portals.
Microsoft later confirmed that the option to activate Windows without an Internet connection via telephone was no longer available after December 3, 2025, but didn’t explain why. However, as spotted by Neowin, the tech giant has now explained in detail why it decided to kill support for Windows activation by telephone in a support article.
Simply put, the company admitted that it deprecated the feature in favor of the Microsoft Product Activation Portal because it provides a “more secure, reliable, and user-friendly” way to activate products.
According to Microsoft:
"Microsoft is modernizing the activation experience for perpetual licenses. Beginning December 3, 2025, the traditional telephone-based product activation automation process has been moved from telephone to online. ... The new digital workflow provides a more secure, reliable, and user‑friendly activation experience and helps prevent fraud. While the process has been updated, offline activation capabilities remain supported. Customers who rely on traditional offline activation can continue using it without changes to their environment. ... The Product Activation Portal enables activation for a wide range of perpetual Microsoft products and supports both connected and non‑connected devices. This evolution ensures activation remains simple, flexible, and dependable while offering a modern, streamlined interface for all users."
It’s worth noting that you’ll need a personal Microsoft account, work or school accounts, Microsoft Entra ID accounts, or Azure Government tenant accounts to access the Product Activation Portal. What’s more, the portal’s signing process included a CAPTCHA, which is designed to make it more secure and also authenticate that a real human is trying to access the platform.
However, Microsoft has indicated that the account used to sign in isn’t tied to your product license, as it’s only used to validate secure portal access.
