How to Reinstall Windows 11 Without Losing Apps and Files

Reinstalling Windows 11: Preserve Your Apps and Files

A severely corrupted Windows 11 system may necessitate a complete operating system reinstall. While a typical USB/CD installation wipes the OS partition, potentially losing data, this guide demonstrates how to reinstall Windows 11 without sacrificing your applications and files.

Method 1: Reinstallation via USB (Offline)

This method is ideal if your PC lacks internet access. You'll need another computer to download the Windows 11 installer and transfer it to a USB drive. The key is modifying the installation to avoid file deletion.

Part 1: Creating the Installation Media

1. Navigate to the official Microsoft Windows 11 download page and locate the "Create Windows 11 Installation Media" section. Review the instructions, requirements, and warnings.

2. Click "Download Now" to obtain the media creation tool.

3. Run the downloaded program (administrator privileges required).

4. Accept the License Agreement.

5. On the "What do you want to do?" screen, select "Create installation media (USB flash drive, DVD, or ISO file) for another PC," then click "Next." If this option isn't available, proceed directly.

6. Choose your preferred media: USB flash drive or ISO file (ISO requires burning to a DVD later).

7. Use a USB drive with at least 16GB of free space. All data on the selected drive will be erased.

8. Follow the on-screen instructions to download the installer to your chosen media. If using ISO, you'll need burning software to create a bootable DVD.

Part 2: Installing Windows

1. Insert the installation media into your target PC.

2. Restart the PC and access the BIOS setup by pressing F2, F12, Delete, or Esc (the correct key is usually displayed during boot). Alternatively, use the "Advanced Startup" option in the "Recovery" menu or press "Shift" while restarting.

3. In the BIOS, navigate to Boot settings and prioritize the USB drive or DVD reader above hard drives.

4. Save changes and exit BIOS.

5. The Windows installer should launch.

6. Select your language and region, and follow the prompts. Crucially, when prompted, choose "Keep personal files and apps."

7. Await installation completion.

Method 2: Using Windows Update (Online)

This method is suitable if you've recently updated Windows and have an active internet connection. It reinstalls the current version, resolving system issues.

1. Open "Settings," then "System," and select "Recovery."

2. Choose "Reset this PC."

3. For automated repair, select "Restart" and allow the fix to apply after the 15-minute download.

4. The download progress will be visible in the Windows Update settings. Restart and update once the download is complete.

Method 3: Windows Restore (May Remove Apps)

This option performs a factory reset, preserving files but removing installed apps.

1. Go to "Settings," "System," and "Recovery."

2. Select "Reset this PC."

3. Choose "Keep my files" and follow the instructions.

Remember to back up important data before attempting any of these methods, as unforeseen issues can still occur.
