However, if you downloaded the update and you’re getting an error that says “This PC can’t run Windows 11”, then know that you’re not alone, but as it turns out, there might be some hidden requirements which could be the reason behind this message. This is according to The Verge’s Tom Warren who tweeted that if you get this error message, your computer might need a TPM 2.0 chip and have Secure Boot enabled in your BIOS.

However, based on the various replies to Warren’s tweet, many people do seem to have TPM 2.0 and secure boot enabled, but they are still getting the error message. Even those with Microsoft Surface devices, which of all devices should have been designed with an upgrade path to Windows 11 in mind, are returning the same error messages.
We’re not sure if this is a bug with the app, but as some have said, Microsoft had similar requirements for Windows 10 but it still installed just fine, and that maybe these requirements are for those in enterprise or for Windows 11 ready PCs, but either way, we’ll have to wait and see.
