Step-by-Step Guide: Upgrading to Windows 11 25H2
  • The upcoming Windows 11 25H2 is set to release in October 2025, marking the fourth major update of the operating system.
  • Users can upgrade through various methods, including Windows Update, using an ISO file, Installation Assistant, or by joining the Insider Program.
  • If you’re currently using version 24H2, the upgrade will be provided as a small enablement package. In contrast, Windows 10 devices must fulfill specific minimum hardware requirements, such as TPM 2.0, Secure Boot, and compatible processors.
  • At this point, 25H2 is only accessible via the Release Preview Channel.

Windows 11 25H2 (2025 Update) is expected to be accessible in September or October of 2025. If you’re looking to upgrade from Windows 11 versions 24H2, 23H2, an earlier version, or even Windows 10, your options for upgrading revolve around Windows Update, the official ISO file, or the Installation Assistant. Additionally, participating in the Windows Insider Program will allow you to upgrade while the update is still in its preview phase.

This upcoming release represents the fourth significant update for Windows 11. However, as it utilizes the same file system as version 24H2, you shouldn’t expect any major new features or alterations. Upgrading will change your version number to 25H2, extend support for an additional two years, and reactivate certain enhancements that had previously been inactive in version 24H2.

Though it can be tempting to install the latest feature update as soon as it’s available, it’s wise to hold off initially to sidestep potential bugs or issues that often accompany early adoption. You can, however, manually upgrade using at least four different methods through various tools and Windows Update. Notably, from August 29, 2025, the only method available for upgrading will be via “Windows Update” settings, provided your device is enrolled in the Release Preview Channel.

The following includes instructions on how to use Windows Update, ISO file, and Installation Assistant for upgrades. These methods will only be applicable once version 25H2 is broadly available to the public in October.

The best approach for those currently on version 24H2 is to use Windows Update, as the upgrade to version 25H2 will be transmitted as an enablement package, negating the need for reinstallation. Opting for other tools will trigger an in-place upgrade, leading to an operating system reinstallation.

If you’re still utilizing Windows 10, you can transition to Windows 11 25H2. Ensure your hardware meets the minimum criteria: an Intel 8th Gen or AMD Zen 2 processor (or newer) and a Qualcomm 7 and 8 Series processor, alongside TPM 2.0, Secure Boot, and a minimum of 64GB of storage.

This guide will illustrate four methods to upgrade to the Windows 11 2025 Update, alongside additional avenues for a fresh installation.
