Depending on your current version and build number of Windows 11, there may be a fast method available to upgrade to 25H2 using an enablement package, because 25h2 shares the same code base as 24H2.

Click your Start Button, then just type winver and press Enter, please provide a screenshot of the resulting dialog box.

Answer 3

If you are experiencing issues installing Windows 11 version 25H2, particularly if the installation stops at 90% or 95% without providing an error code, there are a few steps you can take to troubleshoot the problem:

1. Check System Requirements: Ensure that your hardware meets the minimum requirements for Windows 11.
2. Free Up Space: Make sure there is enough disk space available for the installation. Windows 11 typically requires at least 64 GB of free space.
3. Disable Antivirus Software: Sometimes, third-party antivirus software can interfere with the installation process. Temporarily disable it and try again.
4. Update Drivers: Ensure that all your device drivers, especially graphics and network drivers, are up to date.
5. Perform a Clean Boot: This can help eliminate software conflicts that occur during installation. You can perform a clean boot by disabling all non-Microsoft services and startup items.
6. Use Windows Update Assistant: If the update through Windows Update fails, consider using the Windows Update Assistant tool to upgrade your system.
7. Check for Known Issues: Sometimes, specific issues related to updates are documented. For example, there have been known issues with IIS websites failing to load after certain updates. Ensure that your system is not affected by any known issues that may be causing the installation to fail.

If these steps do not resolve the issue, you may want to consider reaching out to Microsoft Support for further assistance.
