“674M views and they still don’t get the message”: Windows 10 users still aren’t sold on Windows 11

The most-watched video on Microsoft's official Windows YouTube channel has 674 million views since its release on October 31, 2025, promoting the transition from Windows 10 to Windows 11. This video has 48 times more views than the introductory video for Windows 11, which has around 14 million views. Many users remain attached to Windows 10 due to hardware compatibility issues, as Windows 11 requires TPM 2.0, UEFI with Secure Boot, and a supported 64-bit processor. Concerns about RAM usage in Windows 11, which has been criticized for being a memory hog, and a higher frequency of bugs compared to Windows 10, contribute to users' reluctance to upgrade. Windows 11 has stricter hardware requirements, higher RAM demands, a default Microsoft account requirement for setup, and more visible ads and upsells. Although Windows 11 features a more modern design, many users feel that functionality has been sacrificed. Microsoft has committed to improving Windows 11's performance, reporting that it is now up to 20% more responsive in key areas, and users with 8GB of RAM can manage up to 2GB more active data. However, the perception of Windows 11 remains a challenge due to ongoing complaints about its performance and user experience.
