WiseCleaner Checkit is another option for verifying your machine is Windows 11 ready using the currently known criteria.
Checkit is portable, and immediately upon opening, it will begin running through the compatibility checklist. The interface is simple and to the point, providing you with the details of what is and isn't Windows 11 ready. If any of the nine requirements doesn't check out, Checkit shows a brief explanation; for example, while testing in VMWare, our memory was not up to snuff, so Checkit let us know that we need at least 4 GB of RAM.
There are many Windows 11 compatibility checkers out there to choose from, and this one is a solid choice for those that would like to get a jump on making sure their machine is ready.
