How can I upgrade from Windows 10 to 11 for free?

If the Windows 11 Installation Assistant doesn't work, an in-place upgrade using an ISO file is often the most reliable method. This process lets you install Windows 11 directly from the official image while keeping your personal files, apps, and settings intact. It’s also handy if you want to bypass certain glitches in Windows Update.

How to upgrade from Windows 10 to Windows 11 

Step 1. Download the official Windows 11 ISO from Microsoft's website. 

Step 2: Once the download is complete, right-click the ISO file and choose Mount.

Step 3: Open the mounted drive, run setup.exe, and follow the on-screen instructions.

Step 4: When prompted, select Keep personal files and apps so nothing is erased during the upgrade.

In summary, the ISO upgrade method is a straightforward way to move from Windows 10 to 11 for free without losing your data. It uses the same official installation files as Microsoft’s other tools but gives you more control and fewer update errors.
