  • To upgrade to Windows 11 24H2, open Settings > Windows Update > Windows Insider Program, click “Get started,” choose “Dev Channel,” restart the computer, and click “Check for updates” from the “Windows Update” settings.
  • You can also download the Windows 11 24H2 ISO using the UUP Dump script, and then mount the file, and launch the in-place upgrade. 

Windows 11 24H2 is set to be released sometime during the second half of 2024, but the company is also making the feature update available early to test and improve the operating system before the final release, and in this guide, I’ll show you the steps for an early upgrade. 

Although it’s usually not recommended to upgrade early (and more even before the feature update is complete) because of bugs and other issues during the development process, if you want to try the upcoming features, you have at least a couple of ways to install version 24H2. For example, you can enroll your computer in the Dev Channel of the Windows Insider Program and then use the “Windows Update” settings to upgrade. You can also download the Windows 11 24H2 ISO to perform a clean installation or an in-place upgrade. 

At the time of this writing, Microsoft has already confirmed that version 24H2 will release this year. The company isn’t sharing specifics, but the completion of the feature update is expected sometime in April, with a first release in June (for new ARM-based devices) and a final release in October 2024 (for everyone).

The set of new features coming with this release isn’t final, but currently, the company is testing various improvements for Copilot, new Energy Saver mode for laptops and desktops, Voice Clarity to reduce noises with AI, Windows Protected Print Mode, Linux Sudo command, changes for Bluetooth and Sound, and the company is even porting the Color Management settings to the Settings app.

If your computer already supports Windows 11, you can upgrade directly to Windows 11 24H2 since the system requirements still haven’t officially changed.

If you are still on Windows 10, you can upgrade directly, but you must ensure that the hardware meets the minimum requirements. You will need an Intel 8th Gen or newer, AMD Zen 2 or newer, or Qualcomm 7 and 8 Series processor. This is in addition to the requirements of TPM 2.0 and a minimum of 64GB of storage. 

In this guide, I will teach you the steps to upgrade to the next version of Windows 11, coming during the second half of 2024. You can also perform a clean install of version 24H2 with these instructions. If the new version is causing performance issues or compatibility problems, you can uninstall Windows 11 24H2 with these steps.

Important: If you plan to upgrade an existing system, it is also recommended that you create a backup before proceeding. Also, installing Windows pre-releases can cause problems, including data loss.
