How to Get Started with Power BI (2026 guide): Download Guide & The “Desktop vs. Online” Difference

So, you’re ready to move beyond spreadsheets and see what the fuss is about. But when you look for “Power BI,” you find two different versions: one you download to your computer and one you log into on the web.

If you’re confused, don’t worry most people are. This guide will show you exactly how to get the right version for free and explain which one you actually need to use.

1. How to Download Power BI (The Fast Way)

To build the types of reports we’ve discussed, you need Power BI Desktop. This is the “Builder’s Workshop.” It is a free application provided by Microsoft for Windows PCs.1

Option A: The Microsoft Store (Recommended)

This is the best way to download it because Windows will automatically update the app for you every month when Microsoft releases new features.2

  1. Open the Microsoft Store on your computer.
  2. Search for “Power BI Desktop”.
  3. Click Install.

Option B: Direct Download

If you don’t have access to the Microsoft Store (often due to work restrictions), you can download it directly from the web.3

  1. Go to the official Power BI Download Page.
  2. Click Download.
  3. Choose the file that ends in _x64.exe (this is the version for modern 64-bit computers).4
  4. Run the installer and follow the prompts.

Note for Mac Users: Power BI Desktop only runs on Windows. If you have a Mac, you will need to use a “Virtual Machine” (like Parallels) or a cloud-based desktop to run it.5

2. Power BI Desktop vs. Power BI Online: What’s the Difference?

This is the #1 question beginners ask. Think of it like building a house vs. living in it.

Power BI Desktop (The “Builder”)

This is the software you just downloaded. It lives on your computer. You use this to do the “heavy lifting.”

  • What you do here: Connect to your Excel files, clean up messy data, write your formulas, and design your charts.6
  • The Cost: Completely Free. You can use the Desktop version forever without paying a penny.
  • Who it’s for: The Report Developer.

Power BI Online / The Service (The “Hub”)

This is the version you access through your web browser (app.powerbi.com). This is where your reports “live” once they are finished.

  • What you do here: Share your reports with your boss, set up automatic refreshes, and view your data on your phone.7
  • The Cost: Free to use for yourself. However, if you want to share a report with a colleague so they can see it on their own computer, you both usually need a “Pro” license (about £8 per month).
  • Who it’s for: The Executives and Managers who just want to see the numbers.

3. Which one should you use?

The answer is usually both, but at different times.

The standard workflow looks like this:

  1. You open Power BI Desktop to create your report.
  2. You click the “Publish” button inside the app.
  3. Your report is “sent” to the Power BI Online Service.
  4. You send a link to your manager so they can view the report in their web browser or on their phone.

4. Why can’t I just build everything online?

While Microsoft is adding more features to the online version every day, it is still much more limited than the Desktop version.

If you want to do the “clever” stuff—like linking multiple spreadsheets together or writing complex “KPI” formulas—you must use the Desktop version. The online version is great for quick edits or viewing, but it isn’t a replacement for the full software.
