Leaked images of a purported beta build of Windows 11's desktop surfaced online on June 15, 2021,[16] which were followed by a leak of the aforementioned build on the same day.[17] The screenshots and leaked build show an interface resembling that of the cancelled Windows 10X, alongside a redesigned out-of-box experience (OOBE) and Windows 11 branding.[18] The leaked build requires TPM 2.0 to install, a requirement which might be dropped in the final release as most older systems fail to meet it.[19]
