Windows 11 Installation Assistant is officially launched by Microsoft to force trigger feature updates on demand, and for most people, choosing this tool for manual system updates is the easiest option.
How to update Windows 11 to 25H2 manually
- Open Microsoft's official Windows 11 download page, and under the Windows 11 Installation Assistant section, click Download Now.
- Locate the downloaded Windows11InstallationAssistant.exe file and run it, then accept the license terms.
- The Installation Assistant will check your device's hardware compatibility, then download the 25H2 update package and start the installation; the screen will flicker and the computer will restart several times, which may take more than an hour.
Note: Be sure not to interrupt the process, the computer will restart automatically; after the update is complete, you will be automatically logged into the Windows 11 25H2 version, and all files and applications will be retained.
