    WhyNotWin11.exe

WhyNotWin11 is a lightweight system information app that can inform users whether or not their desktop or laptop PC satisfying the system requirements needed for the installation of Windows 11, the latest version of the popular operating system made by Microsoft Corporation. While the official hardware compatibility app exists, developers from Microsoft have decided to simply offer a Yes/No prompt to the compatibility query by the user. On the other hand, this fast and reliable open-source application clearly showcases all hardware requirements and lists what items did user fail or succeed on.

Windows 11 Compatibility Software for PC

WhyNotWin11 is distributed online as an executable file optimized only for Windows 10 and it has no automated installer. Therefore, users can simply download it and place it either on their local storage or portable USB drive. Since this application requires access to the central sections of the OS and tries to perform a diagnostic pass on the motherboard, users will first have to grant this app administrative privilege start. To do so, they simply need to right-click on the WhyNotWin11.exe file and select the “Run as administrator” option. Otherwise, Windows 10 will prompt the user that this application has no official certification and cannot be run.

Once up and running, WhyNotWin11 showcases a simple dashboard with the eleven most crucial hardware requirements that the desktop and laptop PCs must pass in order to be able to install Windows 11. These requirements cover CPU architecture, Boot method, CPU compatibility, CPU core count, CPU frequency, DirectX12 compatibility, Disk partition type, RAM size, presence of Secure boot, TPM version, and amount of available storage.

Windows 11 Minimum Requirements
  • Processor: 1 gigahertz (GHz) or faster with 2 or more cores on a compatible 64-bit processor or System on a Chip (SoC)
  • Memory: 4 GB RAM
  • Storage: 64 GB or larger storage device
  • System firmware: UEFI, Secure Boot capable
  • TPM: Trusted Platform Module (TPM) version 2.0
  • Graphics Card: DirectX 12 compatible graphics / WDDM 2.x
  • Display: >9” with HD Resolution (720p)
  • Internet connection: Microsoft account and internet connectivity required for setup for Windows 11 Home
The app offers no additional functionality. Users can simply see the green, yellow and red notifications near each hardware requirement, and do nothing more. App offers two additional options – a link to visit the official GitHub page where this project is developed in an open-source environment, and a “Check for Updates” button.

WhyNotWin11 is a reliable tool that can help anyone check if their Windows 10 PC is ready to be upgraded to Windows 11. The app is 100% FREE and receives regular updates.
