How to Uninstall Windows 11 and Reinstall Windows 10

This guide will walk you through the process of uninstalling Windows 11 and reinstalling Windows 10. By following these steps, you can revert to Windows 10 efficiently.

Step 1: Back up Your Data

First, back up your data to an external hard drive or cloud storage.

Backing up your data ensures you don’t lose important files during the reinstallation process. It’s a good habit to regularly back up your data anyway!

Step 2: Create a Windows 10 Bootable USB Drive

Next, download the Windows 10 Media Creation Tool from the Microsoft website and use it to create a bootable USB drive.

This tool will guide you through downloading the Windows 10 ISO file and setting up your USB drive, so it’s ready to reinstall Windows 10.

Step 3: Insert the Bootable USB Drive

Insert the bootable USB drive into your PC and restart your computer.

Make sure your computer is set to boot from the USB drive. You might need to enter the BIOS or UEFI settings to adjust the boot order.

Step 4: Begin the Installation Process

When prompted, press any key to boot from the USB drive and follow the on-screen instructions to install Windows 10.

You’ll be asked to select your language, time, and keyboard preferences. After this, click "Install Now" to start the installation process.

Step 5: Choose the Installation Type

When asked, choose the “Custom: Install Windows only (advanced)” option.

This option allows you to perform a clean install, which is often more effective for resolving issues and starting fresh with Windows 10.

Step 6: Select the Partition

Select the partition where Windows 11 is installed, usually labeled as "Drive 0 Partition 1," and click "Next."

This will erase the current Windows 11 installation and replace it with Windows 10. Make sure you’ve backed up your data as mentioned in Step 1.

Step 7: Complete the Installation

Follow the remaining on-screen instructions to complete the installation of Windows 10.

Your PC will restart several times during this process. Once done, you’ll need to set up your user account and preferences.

After completing these steps, your computer will be running Windows 10. You may need to reinstall some applications and restore your backed-up data.
