Repair Windows 11: Upgrade Without Losing Your Files

Is your Windows 11 computer acting up? Sometimes quick fixes don’t work. The good news is you can repair Windows 11 by doing an “In-place upgrade.” This means reinstalling Windows while keeping all your files, apps, and settings safe.

Other ways to fix Windows exist too, like resetting your PC without deleting your data. You can learn more about that here: Reset Windows 11 without losing data.

For the In-place upgrade, you need a copy of Windows 11 called an “ISO file.” This file must match your current Windows edition, language, and version or be newer. You also need at least 20 GB of free space on your main Windows drive.

Steps to Repair Windows 11 with an In-place Upgrade

Before you begin, please check these important things:

  • Turn off or uninstall any antivirus or security software you installed.
  • Turn off bitlocker-encryption-type-on-fixed-data-drives-in-windows-11/" class="sal-link" rel="noopener" target="_blank" data-sal-id="15824">BitLocker encryption if it’s enabled.
  • Download a full Windows 11 ISO file if you don’t have one.
  • Mount (open) the ISO file on your computer.

Once you have done these, follow these simple steps:

1. Open the Windows 11 ISO file

Double-click the ISO file you downloaded. It will open like a new drive on your computer.

2. Run the setup program

Inside the opened ISO, find and double-click setup.exe to start the Windows installer.

If you see a pop-up asking for permission (User Account Control), click Yes. ⚠️ Admin privileges required.

3. Change update settings

When the setup window opens, click the link that says “Change how Setup downloads updates”.

4. Choose Not right now for updates

In the next window, select Not right now. This means the setup won’t download updates, drivers, or extra features during install.
