The question is closed as a duplicate of another question. I have highlighted the difference between the associated question and my question. I have now significantly edited the question to ask how old the CPU must actually be to pass the Windows 11 test? https://superuser.com/questions/1803702/has-the-system-requirement-for-windows-11-changed-since-its-release-if-yes-wha Any chance this could be reviewed for reopening? The question gets locked before I get the opportunity to type in what I think of. I have already thought better of my question. This is what I actually want in the question: Courtesy link: https://superuser.com/questions/1659465/will-my-computer-run-windows-11 Prior to the actual release date, this has been the summary of whether the computer will be able to upgrade to Windows 11. > How do I get a summary of whether my computer will be able to upgrade to Windows 11? There is a Microsoft App (PC Health Check), but I think WhyNotWin11 is more accurate: > > [Why Not Windows 11][8] > > > Study the WhyNotWin11 README file, scroll down to the Download Latest Stable Release hyperlink, download and run it. You will see the dialog below: > > [![Why not Windows 11 screen][9]][9] > > > You see in this screen CPU Generation. This screen came from my ThinkPad X1 laptop, and it meets all the requirements for Windows 11 except for CPU Generation. > > So far as I know now, the CPU must be newer than 3 years old to pass this Windows 11 test. > > We will not conclusively know an answer until closer to the official Windows 11 release date when clearer advice and test apps are available from Microsoft. > > I will typically purchase a commercial grade computer and so for me, four years is not particularly old, but apparently too old to run Windows 11. > > **This has been a summary to help us determine if our computers will run Windows 11.** > > **Follow up Note:** I have today (June 28, 2021) installed Windows 11 Pro pre-release on my Windows Insider machine, and it is working well. Now that is 2 years passed following the Windows 11 release date on October 5, 2021, Microsoft must have clearer advice and test apps. Now, what will be a clearer summary summary of whether the computer will be able to upgrade to Windows 11?
