ufws (UnFuck Windows Setup)

ufws (imagine being drunk beyond all fuck and attempting to say oops) is a simple script to bypass Windows 11 system requirements when upgrading from Windows 10. For clean installation bypass check alternative_bypass.md.

ufws is meant to be used with an unmodified installation medium. Any issues caused by usage of such medium will be ignored. Never use more than one bypass method on single installation medium.

Archival notice

As of build 27686 Microsoft has made changes to the setup process, causing this tool to no longer work. Both ufws.cmd and lufws.cmd scripts are affected. For this reason the project is being archived, as no further development is being planned.

At the time of writing this notice, the only known working bypass for builds past 27686 is the one shown in the alternative_bypass.md file.

Usage

ufws can be used in two ways. You can run it from an administrative command prompt or directly.

Running directly

Place ufws in the root of the installation media and run it as an administrator. It will detect the path and automatically start the setup wizard.

For direct usage from root of installation media you can also use lufws.cmd which is a lite version of ufws with different bypass method.

Running from administrative command prompt

ufws.cmd <install_source_path> [param1] [param2] ...

Examples

ufws.cmd E:
ufws.cmd D:\extracted_iso
ufws.cmd E: /Console
ufws.cmd E: /Pkey XXXXX-XXXXX-XXXXX-XXXXX-XXXXX /Console
