A fresh start is just what you need! If you're dissatisfied with Windows 11's latest updates and want to go back to an earlier version, you can try reinstalling Windows 11 from a USB drive and downgrading to a previous build. Here's a step-by-step guide on how to reinstall Windows 11:
How to reinstall Windows 11 from USB:
- Download the Windows 11 ISO file: You can download the Windows 11 ISO file from Microsoft's official website. Make sure to download the version you want to install, such as the 25H2 build.
- Create a bootable USB drive: Use tool to create a bootable USB drive from the Windows 11 ISO file. This will allow you to reinstall Windows 11 from the USB drive.
- Boot from the USB drive: Insert the USB drive into your computer and restart it. Make sure your computer is set to boot from the USB drive. You can do this by entering your computer's BIOS settings (usually by pressing F2, F12, or Del) and setting the USB drive as the first boot device.
- Reinstall Windows 11: Once your computer boots from the USB drive, follow the on-screen instructions to reinstall Windows 11. This will erase all data on your computer, so make sure to back up any important files before proceeding.
Keep in mind that downgrading to an earlier version of Windows 11 may not be possible if the previous build is no longer supported by Microsoft. Additionally, you may need to reinstall any drivers or software that you previously installed. By following these steps, you should be able to completely reinstall Windows 11 from a USB drive and potentially downgrading to an earlier version if needed.
