Office 2021 Professional Plus Key: Still Worth Buying in 2026?

An Office 2021 Pro Plus key costs $64.99 at The Software City — less than a third of Office 2024 Professional Plus at $199.99. But Office 2021 support ends in October 2026, giving you roughly 6 months of security updates from the time of this writing.

So is it still worth buying? The honest answer: it depends on your budget, your security requirements, and how long you plan to use it. This guide gives you the facts to decide.

Key Takeaways:

• Office 2021 Professional Plus costs $64.99 at The Software City — the most affordable way to get Word, Excel, PowerPoint, Outlook, Publisher, and Access as a one-time purchase.
• Support ends October 2026. After that, Office 2021 continues to work but receives no security patches. For long-term use, Office 2024 Professional Plus ($199.99) is supported through 2029.
• Office 2021 is best for budget-conscious buyers who need full Office apps now and accept the approaching end-of-support date.

Is It Safe to Use Office 2021 After Support Ends?

Office 2021 does not become unsafe overnight when support ends. The risk increases gradually:

Low risk (6–12 months after EOL): Most vulnerabilities discovered are patched in newer versions. Exploits targeting Office specifically are rare for most users.

Medium risk (1–2 years after EOL): Unpatched vulnerabilities accumulate. If you open untrusted documents from unknown senders, risk increases.

Risk mitigation: Keep your antivirus updated, avoid opening suspicious email attachments, and use Office in a non-admin user account.

For perspective: millions of users still run Office 2019 (support ended October 2025) and Office 2016 without major issues. The risk is real but manageable for most personal and small business use.
