Download Office 2021 via ISO

Once you have downloaded the ISO file, installing Office is very easy.

Right-click on the ISO file to mount it to a virtual device. Depending on the utility you installed, you should see the Mount or Burn option. Click on the option or press Enter.

Microsoft 365 vs Office 2021


Microsoft now promotes the “Microsoft 365” subscription service as an alternative to the old Office bundles such as Office 2021 or Office 2019 etc. If you are wondering which one is better, here’s the comparison:

1. Pricing: Microsoft 365 operates on a subscription basis, requiring monthly or annual payments, while Office 2021 is a one-time purchase.

2. Updates: With Microsoft 365, you get continuous updates, including the latest features and security enhancements. Office 2021, on the other hand, provides security updates but may not include new features unless you upgrade to a newer version. Microsoft 365 subscribers always have access to the latest version of Office.

3. Cloud Integration: Microsoft 365 offers robust cloud integration through OneDrive and real-time collaboration tools. This is more limited in Office 2021.

4. Applications and Features: Depending on the plan, Microsoft 365 may grant access to additional applications like Microsoft Teams, SharePoint, and more, whereas Office 2021 provides a fixed set of applications.

5. Sharing: Microsoft 365 subscriptions generally allow installations on multiple devices, whereas Office 2021 licenses are often for one device only.

Microsoft 365 tends to offer more flexibility and a broader set of features but requires ongoing payments. Office 2021 may be suitable for those looking for a one-time purchase without the need for the latest updates and additional collaboration tools.
