Windows 11 and Microsoft requirements are now a common discussion in the forums lately, as the company insists that only with the new hardware you could take full advantage of the improvements of this version.
But there are some who claim that unsupported computers are running smoothly, despite Microsoft's limitations that make it more difficult to install the new operating system on ineligible devices.
This is why the Windows11Upgrade tool is released.
This is an application that allows you to install the new operating system on an unsupported computer. Yes, the free app will allow you to install Windows 11, just as you would with Windows 10.
In other words, you can choose whether you want to upgrade and save applications and data, install Windows 11 by saving only data and not applications, or simply perform a clean install automatically using an ISO of the new operating system.
The system requirements check is bypassed by the application, so even if your computer does not meet them, you will still be able to install Windows 11 just fine. Of course do not try it on 1821 computers.
Microsoft, on the other hand, does not recommend installing Windows 11 on an unsupported computer, but decided to share the steps to do it anyway.
