Deal pricing and availability subject to change after time of publication.This StackSocial bundle pairs Microsoft Office Professional 2021 with Windows 11 Pro on sale for just $44.97 right now (down from nearly $419). It’s the kind of deal that makes sense if you’re setting up a new PC or finally updating an old one. The Office license is for life—no subscription, no annual fees, and it covers all the essentials, including Word, Excel, PowerPoint, Outlook, OneNote, Publisher, Access, and the free version of Teams. Everything installs locally on one Windows PC, so there’s no hopping between browser tabs or worrying about renewing in 12 months.The Windows 11 Pro license, also included, is the full upgrade. It features advanced tools such as BitLocker encryption, Hyper-V virtualization, and Windows Sandbox, making it ideal for professionals handling professional-level tasks or sensitive data. If you’re switching from Windows 10 Home, you’ll notice productivity bumps too: snap layouts, tabbed File Explorer, and Copilot baked into the OS. That last one is Microsoft’s AI helper that lives on your taskbar. You can press the Windows key + C to launch it and ask it to summarize web pages, open apps, or adjust settings—all with plain English. Note that you’ll need at least 4GB of RAM and 64GB of storage to run it, as well as TPM 2.0 and UEFI support; therefore, older PCs may be incompatible. You can only use Office on one PC, and the license is tied to that device, not your Microsoft account, so it doesn’t travel with you if you upgrade to a new computer later. The Windows 11 Pro key gives you a bit more flexibility (it can be activated on up to two devices). And while it’s not compatible with virtual machines or Parallels, the deal still offers solid value for most everyday or professional users looking to avoid recurring costs. Just be sure to activate it within 30 days of purchase.
